We have many large tempdb's totallying 100Gb of space which are allocated on a round-robin basis. For performance reasons we have tempdb's on disk with a cache large enough to cope with the amount of...

Hi, I was at a site where the team achieved a good performance improvement by putting the ASE tempdb devices on a ram disk (in memory). Then tempdb is bound to a small cache. If you reboot the box, the...

Thanks we moved away from tempdb's in memory with a small cache to tempdb's on disk with a large cache as we wanted to cache more data and SAN performance was so slow. On this system, the...

Have you also considered disabling the HK in your tempdb caches? For large volumes of short-lived 'active' pages (in the tempdb cache), disabling the HK can often times provide large reductions in...

Guys, I don't know who is responsible for this interface at SAP side but could you please change its time-out policy? It is very inconvenient to work on cases using this site (or to work on KBAs) when...
View ArticleRe: load database clearing pages message
you can't skip clearing the pages though it would be interesting if there would be a way to do the clearing asynchronously like the way it's possible for create / alter database (option async_init)

Sorry - a couple of questions Whats the best way to see if "the current volume of writes is due to HK activity and not due to a tempdb cache that is too small" ? For most of the time, sysmon shows very...
View ArticleRe: caches over tempdb's
If the cache is too small then you're likely to see pages flushed from cache (to disk) and then re-read from disk as needed; net result is that a too-small cache would see an appreciable volume of...

Completely agree with that. Changing the time-out policy will be great.
