I do think so. It's Core i7 with 32GB memory and SSD. It did not use
much CPU and network bandwidth during benchmark. I'll wait your fix
(seems unrelated, though) and look into what's wrong. I cannot take
realistic benchmark because of this. I might try it on older machines :(

If you could  take simple session benchmark, number of request / second,
it would be helpful for me to know my system's health.

session.php
<?php
//ini_set('session.save_path', '/home/tmp');
ini_set('session.save_path', 'PERSISTENT=1 127.0.0.1:11211');
ini_set('session.save_handler', 'memcached');
ini_set('session.lazy_write', 1);
ini_set('session.use_strict_mode', 0);

session_id('testid2');
session_start();
//$_SESSION['test'] = ++$_SESSION['test'];
$_SESSION['a'] = str_repeat('a', 102400);
echo '<pre>';
var_dump(session_id(), ini_get('session.save_handler'), $_SESSION['test']);
?>

I get about 15K Reqs/sec for files handler with debug build.

Regards.
