Hello, Greg-san > The attached adds two new command line switches to pgbench:
If you are OK, could you make the measurement of time on Windows more precise? The Win32 APIs that pgbench is using for gettimeofday() (in src/port/gettimeofday.c) is much lower in resolution than Linux. The Win32 APIs provide about 15 milliseconds resolution, so I run pgbench -c1 -t16000 the response times of more than 10000 transactions are 0. In contrast, Linux provides microssecond resolution. Please excuse me for making an unrelated request, but this seems to be a good chance... ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
