Re: PHP performance problems with postgres

Hello,

Stupid question, but are you testing in equal environments. For
example, if the Perl script is a CGI is it outputting the same output
as PHP. The reason I ask is that if you were using Perl at the command
line, it will be faster than PHP. This is because you must wait for
your browser to render the data.
