Thanks to everyone who replied. There were some really good points.
However, I found what is causing the difference. The perl program was connecting to the database via a TCP socket while
theC version was using Unix socket. I changed the connect in my perl script, so that it now uses Unix sockets as well.
Runthe tests again and got identical results for both programs.
In case someone is wondering, the way to force DBI to use unix sockets is by not specifying a host and port in the
connectcall.
Cheers,
Val
