Edit report at https://bugs.php.net/bug.php?id=73807&edit=1 ID: 73807 User updated by: pparadowski at media4u dot pl Reported by: pparadowski at media4u dot pl Summary: Performance problem with processing post request over 2000000 chars Status: Analyzed Type: Bug Package: Performance problem Operating System: FreeBSD 9.4-11.0 PHP Version: 5.6.29, 7.0,7.1 Block user comment: N Private report: N New Comment: While testing accf_http module is disabled Previous Comments: ------------------------------------------------------------------------ [2017-01-31 06:53:18] pparadowski at media4u dot pl my /boot/loader.conf is empty. In defaults loader.conf I've got accf_data_load="NO" accf_nds_load="NO" accf_http_load="NO" ------------------------------------------------------------------------ [2017-01-30 18:20:44] rasmus@php.net This sounds like an interesting bug. Since it happens on FreeBSD and not on Linux it might be related to FreeBSD's accf_http "httpready" feature which buffers incoming HTTP requests before triggering the accept. Could you have a look at your /boot/loader.conf file and try disabling accf_http_load if it is enabled there and see if that makes a difference? Note that it triggers a kernel module to be loaded, so you will need to reboot, or manually "kldunload accf_http" ------------------------------------------------------------------------ [2017-01-30 10:58:59] pparadowski at media4u dot pl same problem on php 7.1. ------------------------------------------------------------------------ [2017-01-25 21:42:11] t dot knaur at media4u dot pl Also, this issue causes high cpu usage so in specific situation may result in denial of service. Anyone could help us? ------------------------------------------------------------------------ [2017-01-20 11:03:35] pparadowski at media4u dot pl same on PHP 7.0 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
