Re: [sqlite] Looking for generic speed test results
Thanks Peter, I think that to start with, I am only interested in "generic" amalgamation compilations. These would run the standard TCL test scripts speed1, speed2, speed3, speed4. That would be a good place to start. Noah -Original Message- From: On Behalf Of Peter Holmes I'd be glad to post results for Ubuntu 7.10 on a Dell Inspiron 530 (Dual Core 1.6Ghz) if you're interested. Just supply source code, compile options you want me to use, etc. Noah Hart wrote: > I understand that memory, disk and processor all play a part in the > speed test results.

Almost 10,000 times faster. The difference here is that the "testfixture" program that runs this test is compiled with -DSQLITE_NO_SYNC=1 which disables the fsync() system call on unix, but does not disable the equivalent FlushBuffers() system call on win32. The -DSQLITE_NO_SYNC=1 compile- time option is the equivalent of hard-coding "PRAGMA synchronous=OFF". That's great for testing, but might not be such a good idea for production programs that need to survive power failures. If you want to do a meaningful speed comparison, then speed1.test should probably be modified to set PRAGMA synchronous=OFF. D.
