Hi Mark thank you very much! your answer is very detailed !!!! so : >Based on your link below, you are confusing the specific problems of >running on an active directory server with a problem with the windows >>filesystem cache on 64 bit windows. An issue that has been addressed in Firebird 2.5.2.
that problem is about Firebird , and with that newer versions from 2.5.x to 3 is solved?! but the "solution" was made just by modifing the code of FB or becouse it's needed a specific configuration? >I have no idea what you mean with this sentence. I think you misread the >sentence "DO NOT set up the postgres database server to also act as >ACTIVE DIRECTORY or as a DOMAIN CONTROLLER." in your third link. It >means don't run active directory on the same server as postgresql. The >same advice applies to firebird or any other database server. ok >If you have no other choice, >then at least make sure you are running on a different *physical* disk >then the datastore of active directory (although that is still no >guarantee for good performance). yes that would be my case , my small customers could not make that effort to have 2 servers we are speaking of lan of 3/5 customers. anyway, using a different physical you know that the performance will be the "standard ones" ? phisical disk cold be also a "partition" from the same HDD ?
