Hello Dmitry Thank you for your answer.
I added the settings SharedDatabase = true and SharedCache = false like you told and everything worked fine. Shouldn´t those settings be present in firebird.conf? I had to add them manually. About your question 'why not superserver', I performed two simple tests to measure FB performance, running in the environment that I described. Just one user (me) was connected to the server and no other significant process was running. With these tests, of course, I don´t intended to give the 'final solution' about FB performace. They are simple tests only. I believe better tests could be more illustrative, like processes running at the same time and concurrently, but ... The test: I performed the tests in FB 2.5.3 and FB 3.0.0 First test: I restored the DB from a 'fbk' file. Second test: I runned a very hard SQL sentence using IBExpert. This is what I saw: +------------------+-------------------------------------------+------------------------+--------------------------+ Firebird 2.5.3 : DEFAULT DBCACHEPAGES : Restoring : SQL : +------------------+-------------------------------------------+------------------------+--------------------------+ SuperClassic 4500 21:30 minutes : 02:43 minutes : +------------------+------------------------------------------+-------------------------+--------------------------+ Classic 4500 30:02 minutes : 02:45 minutes : +------------------+------------------------------------------+-------------------------+--------------------------+ SuperServer 122880 32:01 minutes : after 07:50 minutes crashed out of resources: +------------------+------------------------------------------+-------------------------+--------------------------+ +------------------+-------------------------------------------+------------------------+--------------------------+ Firebird 3.0.0 : DEFAULT DBCACHEPAGES : Restoring : SQL : +------------------+-------------------------------------------+------------------------+--------------------------+ Classic : 4500 : 15:20 minutes : 03:05 minutes : +------------------+------------------------------------------+-------------------------+--------------------------+ SuperServer : 32768 : 15:48 minutes : 02:49 minutes : +------------------+------------------------------------------+-------------------------+--------------------------+ Currently I am using FB 2.5.3 and 60 simultaneous connections. Than I ask: should I use SuperServer?
