Slow response time Can't Post

Crazy Would anyone know how to troubleshoot a web host that responds very slowly to cgi scripts? Here's the deal; It's been a couple of weeks since users of my page (www.memudo.com) have been complaining about 'super' slow response times. After requesting my hosting company to look at it (and a million back-and-forth emails and trouble tickets) a friend suggested that we should copy the main page but this time without any scripts, just plain html and images. Guess what, It loads in no-time.

I've been trying to find a way to find out what the heck is happening. I'll very much appreciate your ideas and feedback.

Your main html page seems very slow for me on a cable modem.

Are all cgi scripts slow or just some or one?

Thank you for your interest Paul. The main culprit is a banner rotation script that executes in each and every page (making the entire site almost unusable). I've tried other cgi's with similar frustrating results,

Try this page, which is a copy of the main page w/o scripts;

I'll appreciate your input.

Hi Angelito,

I've tried both pages and the second one is really faster to load (adsl connection).

What does your script do? I mean does it make operations on a database to see what banners are shown, how much times, etc etc or are you just using a flat file?

Try to benchmark your code, and when it is sent to the browser, by putting timestamps at the start and end of the html, and around the place you call the banners routine (for example), maybe it can show up something interresting?

The host seems to have "normal" reply times, but the webserver may be on another machine:

Code
Pinging memudo.com [207.159.140.127] with 32 bytes of data: 
Minimum = 183ms, Maximum = 196ms, Average = 190ms

Pinging perlguru.com [66.70.219.115] with 32 bytes of data:
Minimum = 101ms, Maximum = 106ms, Average = 103ms

Pinging perl.com [208.201.239.56] with 32 bytes of data:
Minimum = 183ms, Maximum = 186ms, Average = 184ms

Pinging userfriendly.org [204.174.18.129] with 32 bytes of data:
Minimum = 188ms, Maximum = 190ms, Average = 188ms


Did you tried to check the time it takes to run other scripts, try for example displaying a random line from a 100_000 lines txt file...??

If you have access to a few tools (or to something like a /proc filesystem) to see the machine's load charge and try to print the results from a script?

my $.02;

Re: [angelito] Slow response time [In reply to] Can't Post

Loaded fairly fast for me for both(cable modem), although the one wo banner was faster. Although cgi is a great choice for banner rotation you might want to look into javascript banner rotation, that way the actual rotation is done once the page is loaded, most sites i go to that receive a enormous ammount of traffic have javascript rotation scripts(which you can usually just "borrow" from view source. Anyways thats my idea on the matter, not sure why the script takes so long, it should be fairly simple, unless it logs banner out, views and all that other stuff.



Hope that helps :)
