Identifying bottlenecks

Finding out what's slowing down scripts

[TGecho]

Are there any general techniques for figuring out where a script is bottling up?

You could profile the script by setting a timer going at the start of the page, then writing out the time elapsed after each major script operation.

Something like:

1. Start timer
<do first operation>
2. Return time elapsed in page
<next operation>
3. Return time elapsed in page
etc.

If you put the timer code in include files it's quite easy to switch into and out of your pages.

Generally speaking, accessing external services e.g. database, ldap, smtp etc will have the biggest performance hit. HTH
