Fix high win cpu use - #9116

I tried "Continuous Build d492ddf" today (with a clean uninstall/reboot/install and a great hope) and I sadly still have 6/7% CPU usage on deskflow-core with TLS enabled (and still 0% with TLS disabled)

I still stick on 1.23.

I wonder if your issue is related to TLS itself.

can confirm the issue is fixed with TLS in the latest build.

Installed 1.25 today and this issue is fixed for my desktop and my laptop, TLS enabled.

1.25 installed too and I Still have deskflow-core using between 4,8% and 5,5% CPU at IDLE.

This issue still exists in version 1.25; my system version is 22631.6199.

try the continious bulid. Please paste a real version info from the application.

Hello =)

This issue still exists in version 1.25 and also in latest continuous version (from this night 2026/01/18) :

• Deskflow: 1.25.0.0 (d4ff55d) / Qt: 6.10.0 / System: Windows 11 Version 24H2
• Deskflow: 1.25.0.165 (aca274e) / Qt: 6.10.1 / System: Windows 11 Version 24H2

CPU goes to 12/13% on my Win_11 x64

Using VisualStudio attaching the process gave me a lot of calls to:

• ws2_32.dll

Using SysInternals ProcessExplorer gave me those calls mainly on the call stack:

• ucrtbase.dll ! wcsrchr
• ws2_32.dll
• deskflow-core.exe ! OPENSSL_Applink

So I disabled TLS on both server (Win11) and client (ubuntu 25.10) and the windows server dropped to 0% instantly.

I didn't want to open a new thread, so I am just adding an answer here.
Maybe admins could open it again?

Hope this helps. For now I will use without TLS !
Have a great day
