• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue Very slow first request for asp.net core site

omuleanu

New Pleskian
Server operating system version
Windows Server 2022
Plesk version and microupdate number
Plesk Obsidian 18.0.45
To isolate the issue I've deployed the default ASP.net Core site from Microsoft (2 empty pages With "Hello World" on them) on plesk.
The first request, after some inactivity takes a very long time, from 10 seconds to 1.4 minutes, usually 15 ~ 25 seconds.
Without having to wait I can reproduce this issue by modifying the web.config (add an empty line at the end), this will make an asp.net site restart.
After the first request the site will load in 0.2seconds.
