No, but I'm just testing my patch on Linux-2.4 with a middle-range server.
I will report the results sometime soon.


By the way, I found the debug option (XLOG_MULTIPAGE_WRITER_DEBUG) was enabled
in your prior benchmarks. It writes logs a lot.
I hope performance doesn't fall at least without debug.

That's 'log_min_messages = debug1' right? Maybe I should give it
another go with that set back to the default.

Thanks,
