Performance degradation since 2026.1
After upgrading teamcity to 2026.1 we noticed a large performance degradations where our jobs are taking twice as long to complete:
There are no changes in packages outside of the update of teamcity to 2026.1. and the agent running java 21.
VM has no changes. Using a dedicated VM.
The codebase had no changes the first few runs, and even those were slow.
Not seeing any changes in CPU or memory metrics since upgrading.
VM is using 8 cpu's and 32 gb memory.
Has anyone seen the same issues?

Hi,
Could you please share with us a build log from before the upgrade and a recent one from a build configuration where you see this performance degradation? Please share them with a few agent thread dumps captured during the recent build, together with the build agent logs. You can share them to our secure upload service and share the upload ID with us in this thread:
