I am going to compare a 16KB PostgreSQL system to an 8KB system. I am working on the assumption that 16K takes about as long to read as 8K, and That the CPU overhead of working with a 16K block is not too significant.
I know with toast, block size is no longer an issue, but 8K is not a lot these days, and it seems like a lot of syscall and block management overhead could be reduced by doubling it. Any comments? The test system is a dual 850MHZ PIII, 1G memory, RedHat 7.2, 2 IBM SCSI 18G hard disks, intel motherboard with onboard adaptec SCSI ULVD. Besides pgbench, anyone have any tests that they would like to try? Has anyone already done this test and found it useful/useless? ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
