Re: Timing concerns on PerlEX/Mod

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;
[download]

at the beginning, and an analogous

  warn "End: " . Time::HiRes::time;
[download]

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.

Yes I did that already. My script takes 0.3 seconds average beginning to end. Which is fine, but when I LWP remotely and do a check. I get times from 2.5 seconds to 200 seconds(but in both cases script is still 0.3 seconds from beginning to end), also my ping seems same as google or around, so not a latency issue. (google.com LWPs for around 2.5 seconds). So if my code is taking only 0.3 seconds, I assumed it was IIS, so I swapped to Apache/ModPerl and am getting the same issue. I only have one script, which then loads preloaded html files and outputs them.It had a main namespace which has the output, and then a common name space where lal the common functions are stored and called. The output I'd say isn't that big, less then 30kb i'd say. I am not seeing anything strange in error logs	[reply]
