Hello Jeff,
Thanks for your valuable input, I’ve tried to reflect it in my new config.
Yes our application use heavily temp tables (with 1 index); I’ve changed the tmpdb to an In-memory one. I’ve changed also the 'session tempdb log cache size'
The memory should not be an issue as I’ve 256GB on the server and ASE is configured with 48GB (vmstat report 64 GB of free memory) ; that’s why I didn't take time to tune the buffer pools (and this stress test only exercise a part of the application)
So now, I’ve highly reduced the Fully Logged APL Insert & Delete but not all of them and neither the Updates.
I’ve also noticed a very high (80%) of “ULC Flushes to Xact Log” “by Log markers”, which is documented as “When “by Log markers” displays a large percentage of ULC flushes, you may need to reduce the number of unnecessary or redundant triggers, rollbacks, or aborts. “
But IFAIK, there is no trigger on temporary tables, and rollback or abort should not be present, so I don’t know how to identify this problem; can you give me some hint ?
I attached the new config, logfile, sp_sysmon and sp_configure of the current config.
Thanks for your help.
