Re: PHP 4.0 Bug #2806: Processor Usage

We need more information on this (since generally PHP 4.0 is much faster than 3.0). It could be a misconfigured installation (even though frankly, I'm not sure how it could cause that) or it could be something unique to your scripts (or it could be a weird bug). Please provide us with more information, for example, an example script that runs (considerably) slower under 4.0 than it does under 3.0. Also, please try to see if your machine is low on memory, and whether PHP (or httpd) processes consume lots of memory. Finally, make sure PHP 4.0 was installed with debug turned off (--disable-debug), the default for the beta builds is to enable debug information, which greatly reduces performance.

Operating system: Sun ultra spac

PHP version:      4.0 Beta 3
PHP Bug Type:     Performance problem

Bug description: Processor Usage My ISP at Digital Nation (dn.net) installed the new php4 beta 3 on my Sun UltaSparc over an existing copy of php3. All the old php3 scripts run with php4, but extremely slow. I get high traffic to the site and it works fine on php3. With php4 each request takes up huge % of the cpu and causes the processes to pile-up and clog the system. The only other server that I am running is mysql on apache. When I reload php3, everything goes back to normal. -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: php-dev-unsubscribe@lists.php.net For additional commands, e-mail: php-dev-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
