Summary: curl extension slows down PHP
Status: No Feedback
Type: Bug
Package: cURL related
Operating System: win32 only - Windows 7
PHP Version: 5.2.11
New Comment:
The same thing happens on my system.
Windows 7 x86, PHP 5.3 (5.3.2) VC9 x86 Thread Safe (2010-Mar-04
20:11:10)
After some debugging of php I found out that the RAND_screen() function
in
libeay32.dll is responsible for slowing down the execution.
I've patched the function out, and it really became fast again. I don't
use SSL
stuff so I don't care how this affects security.
The patch is 0xE8 -> 0xC3 on offset 0x0003EE10, you can use it as a
temporary
solution (patch it with any hex editor).
Cheers!

I am using PHP as embedded in another Win application.
I can confirm that the issue occurs both from cli and embed sapi.
I have tried different versions and also found that the issue started
with 5.2.11 and is present up to 5.3.1

I'm not the original reporter, but I cannot confirm that the bug affects
requests when running PHP as an Apache 2.2 module, only that Apache
start/restart is noticeably slower with curl enabled.
Is there more initialization code now than there was in 5.2.10? I ran a
diff of /ext/curl/* between 5.2.10 and 5.2.12 and didn't see anything
significant.
I just tested PHP 5.3.1 and sadly the bug exists there too. :(
(I'm calling it a bug because the cause of the delay is still unknown)

I don't think it happens during all requests but when you start apache
(as running CLI).
Can you confirm that the slowdown happens on all requests and not only
on apache start?
PHP's curl does some initialization, just like many other exts.

I'm also having this problem, with a freshly-extracted copy of
php-5.2.12-Win32.zip (php.ini edited to enable curl). In my case the CPU
spike lasts about 2 seconds (just running php.exe -v), but that's a
significant delay for someone who runs CLI scripts often.
It seems to only affect PHP 5.2.11 and 5.2.12, as I wasn't able to
reproduce it with 5.2.10 using the exact same php.ini file.
Confirmed on Windows 7 and XP.
