There are several tools available for bench testing. pgbench seems like a pretty good one for measuring database performance since it uses libpq interface. Would you concur?
At this point I'm not concerned with comparing interface performance(i.e. JDBC, ODBC, C++), C++ is bound to be the fastest. Also not concerned with network or user interaction aspects of performance...yet. Does anyone know how the "other reports" were gauged? Apparently, I am not the _only_ one who has reproduced these results using pgbench.
