Anyone got a link they would like to share on how to read and interpret the results of dm_os_performance_counters
Today I ran into some performance issues with SQL slowing to a crawl for a few processes.
I know there are several tables that need their indexes rebuilt, and its on the to-do list to get these cleaned up when we can have some scheduled down time.
However, in general, what are some things you can look at to get an idea of where SQL is having trouble, at a system level.
Memory use, Disk use etc...
Ive been reading a bit about using Permon...but wont that affect performance itself?
