Topic: CPU overusage.

[SoMDWx]

Hello All,
  I am hoping some of you PHP/AJAX gurus can assist me with this issue.

I am using the AJAX script to update my main website page with the latest data from my VWS files.

I received a notice the other day when we got nailed with a big snowstorm here in So. MD that my site had gone WAYYYYYYYYYYYYYYY over my CPU limit (100 minutes/day)  for the day. They restricted my site to just 5 simultaneous processes.

I was told that 2 PHP scripts were the cause of the issue.

I modified one of those to use static data that VWS creates..

The one which contains the live update is still running...

Is there something I am missing here with the script that would cause such over usage?

Thanks!

Jim

Hi Jim,
I'm a bit confused.  AJAX (JavaScript) runs in a browser and just reads a file from the site (and shouldn't cause a 'CPU Overload').

Do you have a script that is invoked by VWS to push the current conditions to the website (via a GET-mode URL) like the WeatherFlash update script?  Is that the script causing the issue?

It would help if you posted the (expurgated of user:pass info) code of the script(s) that seemed to be causing the issue, along with how they are invoked (by the website page or cron or VWS)

Best regards,
Ken

Ken,

The file is a PHP files which invokes the ajaxVWSwxs.js.  I can send both files to you if you wish.

Gotit.. fixed one script for you.. see email.

Problem was a script was accessing an external website each time it was loaded.. that can cause backups as multiple outbound connections for the same data can be generated.  Changed the script to use caching and auto-refresh at 1800 seconds for the result.
