Hi,

I have a problem that could be a bug, or maybe not. I was hoping to get 
a little feedback on ways I might go about figuring what my problem is.

I've already posted this to PHP-General ( 
http://marc.theaimsgroup.com/?l=php-general&m=115859850619474 ), with 
not a lot of luck. some details are re-iterated here.

I have a site that reads an xml feed from an external website, parses 
it, and displays the result. It seems to work well, if a little 
unoptimally, but occasionally the script just seems to pause. Using 
microtime() at various points in the page I've found that it just seems 
to wait (as if it were waiting for a lock or something). This seems to 
occur multiple times at multiple points in the script, adding up to a 
very slow script execution overall. It seems to average about 45-60 
seconds, as opposed to the 0.5 - 1.5 it normally runs in. I've tried 
using APD, but it just told me what I already knew, at random points in 
the script it's just taking a long time.

I think the next step is probably the PHP-Internal debugger, but I have 
no clue how to use it, is there a resource available that might help me?

Thanks, I apologize in advance if anyone thinks this doesn't belong in 
the Internals list.

Chris
