• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Hi,

I have the problem that I can not enter more than 100 with the limitation of the CPU value. My system has 8 threads.

How can I enter a higher value?

Hi B4c4rd1,

pls. don't get this wrong: What happens when you try to enter MORE water in a glas, even when it's already filled up completely? Correct answer will be: The excess water flows past the glass.
You can't use more than 100%, because 100% is the technical maximum. ;)

Hi @UFHH01,

The documentation of plesk states the following: The CPU capacity is specified in percent, and 100% of CPU limit is one core fully used. Correspondingly, 200% is two cores fully used, and so on.

My tests have shown that actually only one core is fully utilized when I enter 100%.

My CPU Set has 4 Cores with 8 threads.
 
I have forwarded this issue to developers for the further investigation. Will keep this thread updated.
 
I found a next issue.

If I once entered a value on disk read and disk write, it remains stored even when i go back to unlimitiert.

Test it:
insert the Limit 50MB -> save.

Make sure the cache is cleared (On root shell):
Code:
echo 3 | sudo tee /proc/sys/vm/drop_caches

Check with the following command (On limited user shell):
Code:
dd if=tempfile of=/dev/null bs=1M count=1024

With Limit:

Without limit ( Unlimited checkbox)

Can someone confirm this issue? Or should I open my own thread for it?
 
Regarding initial issue - bug was confirmed and submitted as PPP-28283.
