Questions: 1) This is an OSS project. Why not just recruit a bunch of people on PERFORMANCE and GENERAL to test the 4 different synch methods using real databases? No test like reality, I say .... 2) Won't Jan's work on 7.5 memory and I/O management mean that we have to re-evaluate synching anyway? -- -Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
