We are currently running with the default size (2K) on "session tempdb user log cache". We are planning to go to 128K. We know this is going to burn some cache but still worth it as it reduces persistent issues with tempdb log management.
Though we do not envision any issues just want to check with the ASE community on their experience with this...
Thanks,
Prasad
P.S: Thanks to Jeff T for nudging to take this route.
