[xdebug-general] Re: xdebug causing PHP to run very slowly

Wow Bill, thanks for the tip on strace. Never used it before...

Hung on
connect(3, {sa_family=AF_INET, sin_port=htons(9000),
sin_addr=inet_addr("192.168.1.101")}, 16) = 0

192.168.1.101 is MY computer, which is ALMOST ALWAYS running an IDE set
up to take data from a debugger...
But it wasn't in this case. Started up my IDE and pages flow normally.

Maybe not how yall have this set up, but I'm using a linux server for my
test machine, and programming on a windows box.

Anyway, I just turned off remote_enable and I'll use the cookie method
to turn it on as needed.

Thanks!

I don't know the answer to your problem, but I'll throw out some guesses
and suggestions.

First off, I use xdebug quite a bit and have never seen this problem, so
it's not typical.

Do you possibly have xdebug configured to write data to a file that it
doesn't have write access to? That "hang" behaviour is indicative of
something in the code that's timing out (actually, sounds more like a
DNS query timeout, but I'm not sure if that can happen in xdebug. Make
sure your server has a hostname that resolves via DNS, though.)

What OS are you on? Can you run a ktrace/strace on the xdebug process
and see if there's a particular syscall that is causing the hang?
