Use Measure-Object to count things. In this case it would look like:
Only Files
Get-ChildItem c:\MyFolder -Recurse -File | Measure-Object | %{$_.Count}
Only Folders
Get-ChildItem c:\MyFolder -Recurse -Directory | Measure-Object | %{$_.Count}
Both
Get-ChildItem c:\MyFolder -Recurse | Measure-Object | %{$_.Count}Specific files
Get-ChildItem -Path c:/MyFolder -Recurse -filter *.xml | Measure-Object -Property Directory
Once on you have booted to BIOS.
1.Enter into Advanced Mode
2. Expand CPU Configiuration
3. SVM Mode => Enabled
4. Save configuration and restart
Somehow I always seems to struggle to center block elements so I write a small note (mostly for myself) how to do it.
div{
margin-left: auto;
margin-right: auto;
}div{
display:flex;
height:100vh;
align-items:center:
justify-content:center;
}div{
display:grid;
height:100vh;
place-items: center;
}
I noticed that WordPress and WordPress Multisite on Azure does not perform well. It seems that anything written in PHP is not the first class citizen on Azure and PHP runtime as well as MySQL behaves differenly on Azure than running it on VM or Docker.
I was not able to make WordPress as fast as it would be on VM but I got close. Please notice that I am running App Service under Windows Operating System. If you have change to run this under Linux you will likely get much better performance and some of the tips below may not be relevent for you. In any case fine tuning these settings are always solution specific but if you have performance problems I hope my findings helps you.
App Service
You should run the App Service in minimum P1V2. Everything smaller in a bigger solution becomes slower. This gives 210 total ACU 3.5 GB memory for the app.
Azure Database for MySQL server
Gen 5 with 100 GB and 4 cores seemed to work for me. I noticed that there was not much of difference if you choose Basic with 2 vCores. If you don’t need large storage I recommend trying out Basic first but notice that you cannot scale from Basic to General Purpose with a click of a button. It requires moving db’s manually.
Changes Made:
Open the solution in Kudu or FTP client and create new folder at d:\home\site\ini on your app structure. Under new ini -folder create settings.ini and add following settings:
wincache.maxfilesize=1024M
memory_limit=2048M
upload_max_filesize=50M
post_max_size=50M
max_execution_time=3600
max_input_time=300
output_buffering = Off;wincache.maxfilesize
– Defines the maximum allowed size (in kilobytes) for a single file to be cached.
memory_limit=2048M
– This sets the maximum amount of memory in bytes that a script is allowed to allocate.
upload_max_filesize, post_max_size, max_execution_time, max_input_time
– You may not need this. I got some bigger file execution operations in relation to a WP plugin that required extend size and execution times. Not exactly related to performance.
output_buffering
– I don’t really understand why this is set on Azure. App seems to run better if it is disabled?
After adding the settings.ini under d:\home\site\ini\ folder open App Service > Configuration > Application Settings and the folder to the key called PHP_INI_SCAN_DIR=d:\home\site\ini\ like this:
Save and restart the App Service. Now you should have custom INI for your app where you can adjust default PHP settings.
You can verify that your settings are correct by creating phpinfotest.php with <?php phpinfo(); ?> in it and uploading it to the webroot. Then on your browser you can see this file and see all your settings.
I have tried both of these and neither them helped me but it might help on some installations. So I will write few words about them
App Service Local Caching
The Azure App Service Local Cache feature provides a web role view of your content. This content is a write-but-discard cache of your storage content that is created asynchronously on-site startup. When the cache is ready, the site is switched to run against the cached content. Enabling local caching will change how the storage works for your app service. This is only recommended for more static WordPress instances and not for WordPress instances that have new posts or pages.
To enable it add these settings to your application settings
WEBSITE_LOCAL_CACHE_OPTION Always
WEBSITE_LOCAL_CACHE_SIZEINMB 2000
I have heard and read this is great setting on some solutions but for me performance got 10 x worse with local caching. So I drop it.
Redis Object Cache
Object caching allows your web application to cache the results of queries as objects in low latency memory based storage. But this is also something that may not work for your solution. I did not have good luck on my solution, on my instance speed got 10-15% slower after enabling Redis. There are a few caveats to using the Redis Object Cache approach on WordPress. The caching mechanism does not work well if you have a lot of plugins and themes installed. This is due to the fact that all their data would need to be cached as well with Redis. But it is worth of testing since Azure Cache for Redis is easy to setup and test it. If you don’t see benefits on it you can just delete it. I followed this blog post to configure caching with Redis.
If you have a lot of visitor on the site I think you should definetly evaluate Redis.
I tested different cache plugins that work with WordPress Multisite and I settled with WP Super Cache. This plugin is simple and quick to configure. If you install the plugin and just enable it it works. Only custom setting I added was in the advanced section I extended cache recycling to 1 hour.
Azure Content Delivery Network (CDN) lets you reduce load times, save bandwidth and speed responsiveness. You can use the same cache plugin WP Super Cache to enable CDN.
A few tips to improve WordPress performance and overall settings on Azure Web App are listed below:
<requestFiltering>
<denyUrlSequences>
<add sequence="xmlrpc.php" />
</denyUrlSequences>
</requestFiltering> <staticContent>
<mimeMap fileExtension="woff" mimeType="application/font-woff" />
<mimeMap fileExtension="woff2" mimeType="application/font-woff2" />
<remove fileExtension=".mp4" />
<mimeMap fileExtension=".mp4" mimeType="video/mp4" />
<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="7.00:00:00" />
</staticContent>It is possible to get decent performance on WordPress solutions on App Service but I am still in doubt if this is the better solution than running on Virtual Machine or in the container. I never was able to get close to performance that I can get on Virtual Machine with dedicated application server and MySQL server under Linux. Although, Azure is getting better and faster everyday and there is no doubt that eventually it will be at least as fast as VM.
The Az PowerShell module has been for a while the recommended PowerShell module for interacting with Azure. Here is the quick guide how to install AZ on Windows 10.
Powershell script to un-install Azure/AzureRM and install AZ
# Remove base modules:
uninstall-module Azure
uninstall-module AzureRM
# Remove the rest
$Modules = Get-Module -ListAvailable | Where {$_.Name -like 'AzureRM.*'}
Foreach ($Module in $Modules) {Uninstall-Module $Module}
# Install AZ
if ($PSVersionTable.PSEdition -eq 'Desktop' -and (Get-Module -Name AzureRM -ListAvailable)) {
Write-Warning -Message ('Az module not installed. Having both the AzureRM and ' +
'Az modules installed at the same time is not supported.')
} else {
Install-Module -Name Az -AllowClobber -Scope AllUsers -Force
}
# Connect to Azure with a browser sign in token

I haven’t seen many posts about Continuous Integration. Perhaps this is because Umbraco Cloud option offers this feature off the shelf but I have some customers that require customizations (custom databases) that would be costly on the Umbraco Cloud setup. Therefore I decided to spin up Jenkins that connects to Github repo and does automatic deployment from the main branch whenever there is push to it.
Here are few quick steps that gets you started.
Wheater you use Github or Gitlab or your own Git repo these steps do not matter. You just need a branching stradegy where the master branch matches what is in your live site.
Merge feature branches into the master branch using pull requests.
I have root server Windows 2019 running on Hetzner but I hear OVHCloud is good as well. So, I installed Jenkins instances directly on my test server and live server. I could do the setup with PowerShell remote but Jenkins is quick to install and requires very little maintainance and resources so I just have them running isolated on the given server.
In the Jenkins server you also need Microsoft Build Tools and Nuget installed on globally available.
You need some plugins in order to build .NET projects and Frontend projects. Try these:
Here is my sample configuration on Freestyle Jenkins project.
Node version
Nuget restore command and Injection to Assembly
Run MSBuild
Copy files from Jenkins build folder to Webroot
Stop-WebAppPool -Name "DefaultAppPool" you may make restarting of the application few seconds faster that way. But you need to stop AppPool or IIS because sometiimes artificats are locked and if that happens things goes south.Post Build actions
That’s it. Minimail Jenkins setup for Umbraco projects that I use. This same setup works for any .NET projects as I did not include any actions on uSync or anything other Umbraco specific.
I have done few DevOps Setups on Jenkins, TeamCity, Azure Devops and Github Actions. Which ever CI/CD tool you are using I recommend to create your scriptinigs on Node and/or PowerShell so you can easily jump between as they all work essentially same way.
Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells).
| Description | Command |
|---|---|
Start a new session with session name | screen -S <session_name> |
| List running sessions / screens | screen -ls |
| Attach to a running session | screen -x |
| Attach to a running session with name | screen -r <session_name> |
| Detach a running session | screen -d <session_name> |
When you do nested screen, you can switch between screen using command “Ctrl-A” and “n“. It will be move to the next screen. When you need to go to the previous screen, just press “Ctrl-A” and “p“.
To create a new screen window, just press “Ctrl-A” and “c“.
There are 2 (two) ways to leaving the screen. First, we are using “Ctrl-A” and “d” to detach the screen. Second, we can use the exit command to terminating screen. You also can use “Ctrl-A” and “K” to kill the screen.
That’s some of screen usage on daily basis. There are still a lot of features inside the screen command. You may see screen man page for more detail or this page https://gist.github.com/jctosta/af918e1618682638aa82.
