Performance differences after starting the system

GLASS mailing list

Just to give a hint, how a filled cache can improve the responding time of Gemstone.

I've started a stone and made a query over the whole data and the following time was recorded:


first time:  360 seconds

second time: 6 seconds

third(++) time: < 1 second


after some time of no action the responding times went down again, but not as much as when executing it for the first time. This has been measured on a hosted system with 8GB RAM, 4 cores and HDDs.


Wasn't there an option to warm up the chached memory ?


Marten
