| I gotta agree with Laura, developers need to learn how to page there queries to AD, its not recommened raising the page size above 1000, for all the "No" responses that Laura has dictated. PHP, or whatever seen a lot of this you basically got to tell the vendors they need to page there queries and they start to understand they need to change there code a little and make it work correctly.

I will channel the spirit of joe Richards until he reads this thread and responds to it himself:
Raising the page size? No. No no. No no no. No no no no. No no no no no. Did I mention...no?
Even if raising the page size from 1000 to 1500 doesn't create perf issues for you initially, it sets a bad precedent. You set your max pagesize to 1500 to fix this script issue. Then next month there's another script/app for which 1500 is too small, so the developer asks you to raise it to 2500, or 3000 or 5000.
At some point, and probably sooner than later, you're going to start clobbering your DCs. Much better to have your apps/scripts use paging, as it's much more predictable and well-behaved.
NB: I will admit to knowing absolutely -nothing- about PHP and so I can't unfortunately instruct you on how to enable paging in your script. I have to believe there's a way to do it, though.
