I wanna go faster!!

[jez]

Hi there,

I have a script running on web server performing a search type facility. It works great but can be a bit slow. This is probably alot to with the server itself (and it's hap-hazard configuration) but I wanted to know if there are any ways I can go about trying to speed up the execution of my script.

The error logs show that although it runs, the script still produces errors...these are mainly "Name main::var-name used only once, poss typo" and it does this for all my global variables...I'm not using Strict, should I and are these errors anything to worry about since the script works?

Any tips on performance would be greatly appreciated.

Many Thanks

Jez

While the program is actually in use, it's not necessary to use strict as it just creates extra overhead. However, I would always use it when creating/debugging a program, so you may consider implementing it now (on a copy of the working version ... don't want to break the running code).

Global variables, generally, are not a good thing even though their use is valid in Perl... Hence the pseudo-error. There are a couple of reasons for this:
1. It's easy to forget what variables are currently in use and thus, overwrite them, causing the script to crash, enter an infinite loop, or become terribly depressed.
2. Garbage collection can't touch these variables which can lead to high memory usage and low efficiency. Garbage collection waits for all references to an item to go out of scope ... something global vars don't do until the end of the script.

Why don't you post the code, or a link to the code source so we can better evaluate your options?

Thanks for the tips, I have emailed the entire script directly to you FYI.

In the mean time though, now I know the way to use strict I can start making this script a bit more bullet proof.

Anyone who would like to see this script for ideas or whatever please email me ..... jmanse@hotmail.com (mainly because the script is quite long to post here.

Thanks again

Jez

You could always use FastCGI Mode. Try fastcgi.com
