Status: Verified
Bug Type: Performance problem
Operating System: win32 only
PHP Version: 5.2CVS-2008-08-10
New Comment:
It seems it's a php_strtolower() issue because we have the same problem
by replacing stripos to strtolower...
The problem occurs on Windows also with strtolower()...
71 seconds on Windows, 25s on linux...
Reproduce code:
$a = str_repeat('x', 100000);
for ($i = 0; $i < 10000; $i++) {
$b = strtolower($a);
}

Description:
------------
stripos() is very slow on Windows, about ten times slower than on
Linux.
Reproduce code:
---------------
$a = str_repeat('x', 100000);
for ($i = 0; $i < 10000; $i++) {
$b = stripos($a, 'y');
}
Expected result:
----------------
On Linux it takes about 3 secondes.
Actual result:
--------------
On Windows: 30 seconds
