In other words, what Roger is gently trying to tell you is to test yourself before asking. You are the best judge of your conditions, your machines, your application. Testing is the surest way to find out the most appropriate answer for your situation. Change the cache_size then test. Then change again and test. Soon you will know the answer. You can then come back and ask the list, providing results of your test, and then folks might be able to guide to a better solution. > JP > > > > > > From: Roger Binns > To: General Discussion of SQLite Database > Sent: Monday, April 20, 2009 5:11:48 PM > Subject: Re: [sqlite] what is the right cache_size for sqllite version 3.5.9 > > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA1 > > Joanne Pham wrote: >> It it the right size for the cache_size?

[sqlite] what is the right cache_size for sqllite version 3.5.9
Hi All, I am currently using sqlite 3.5.9 and I have set the cache_size as below: sqlSt = sqlite3_exec(pDb, "PRAGMA cache_size = 2000 ", NULL, 0, &errMsg); It it the right size for the cache_size? My applications have a lot of writes operations and can be up to millions rows per minutes. Thanks, JP ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
