After upgrading to Acumatica 2025R2, some of my users started experiencing random slowdowns. Each week, one or two users report performance issues, but when I check the PCs and the server, neither is running at full capacity. I’m not sure what’s causing it

Random Slow performance in Acumatica 2025R2
Best answer by Abhishek Niikam
Hello,
-
Ignore this 3005 event - it’s noise, not the cause.
-
Check IIS pool recycling settings.
-
Run network stability tests for affected users.
-
Check Acumatica trace logs for slow DB operations.
-
Verify browser and cache conditions.
-
If it continues, enable SQL Server Extended Events to trace latency.
I hope it helps!

I saw this warning login in event viewer of server. I don’t know it’s related this the problem or not.

IIS pool recycling settings. Is it right ?
+16IIS pool recycling settings. Is it right ?
This is the default setting.
But if you do the math (1,740 / 60), this is 29 hrs. That means that periodically (and for several days in a row), the recycle (which is essentially a restart) will probably occur over the time it’s being used.
If this is a server in production, I would recommend setting this to 0 and using the Specific Times section to specify a time when the server isn’t being used.
