There is another tool that says how much time is used on each zone or call. Ah, a profiler. Maybe thousands of calls to the same function is the issue, or maybe not because the i/o is cached.
But I don't remember how to use a profiler in Linux this instant.
If it were C-code, no problem, but it's PHP. Regardless, it's not so important how much time is spent where, it's about reducing the time from 4 seconds to 1 second.
Well, exactly. Find out the line(s) in the source code where most time is spent. Hopefully those 4 seconds are lost in a small section, even a single line, perhaps a loop. Once found, the code can be changed. Unfortunately, it is php code. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
