- How much output are you generating from these scripts?
- Have you been able to profile the areas where your application is spending its time?
- What are the logs saying?
- What type of input is being sent to each?
Try putting a
use Time::HiRes;
warn "Begin: " . Time::HiRes::time;
at the beginning, and an analogous
warn "End: " . Time::HiRes::time;
at the end of the called portions of your script (if there are blocks that are called each time before and after execution, those would be ideal locations - not knowing what they are, if they exist, I cannot say) will at least give you a feel of how much the perl side is contributing to the delay.
There are quite a few points where things other than the Perl script contributes to the delay. Look at the time spent in Apache/IIS, the OS TCP/IP stack, and the client side of things as well. All things work together for the delay of those who write code.
