Worktables FROM Cache Ratio
Hello. For some reason, one of my MS SQL 2019 runs shows that the "Worktable Ratio from Cache" is around "62%". I checked that no parameters were changed. My programmer says they don't change anything. Since I have no experience as a DBA, I would welcome any hint of what I might be research next.
In sys.dm_os_performance_counters i see
Worktables From Cache Ratio 4964
Worktables From Cache Base 8002
I assumed there was not enough memory, but Buffer cache hit ratio is around 100%
Buffer cache hit ratio 14529
Buffer cache hit ratio base 14529
- olafhelperBronze ContributorAnd what exactly is the problem here? Do you have any performance or other issues?

No. There are no problems with performance, it just suddenly dropped from 92% to 62% after a reboot and does not rise. On other servers, this value also drops when rebooting, but gradually returns to normal. I'm afraid this is some kind of symptom.
