The Win32 APIs that pgbench is using for gettimeofday() (in src/port/gettimeofday.c) is much lower in resolution than Linux.

I wasn't aware of this issue, and it certainly makes the whole latency side of pgbench pretty useless on Win32. There is code in src/include/executor/instrument.h that uses a higher resolution Windows timer API than gettimeofday() does (as you point out, that one is only resolves to one Windows tick, about 15ms). If I can get a Windows build environment setup, I'll see if I can borrow that solution for pgbench.
