Previous Comments: ------------------------------------------------------------------------ [2018-01-29 17:31:54] fortwebsolutions at gmail dot com You are correct, i had to add the user apache was running as a sudoer, i know this is not optimal. Maybe there is a was to allow the apache user to run nice without the sudo, but that is not the point. The slowness of exec() is do to low process priority and is not actually a bug in either PHP or apache. ------------------------------------------------------------------------ [2018-01-29 16:44:10] spam2 at rhsoft dot net and no webserver setup would allow "sudo" anyways ------------------------------------------------------------------------ [2018-01-29 16:41:49] spam2 at rhsoft dot net https://stackoverflow.com/questions/14277910/php-exec-performance/48505455#48505455 is nonsense because the command on the left side is ececuted and than the output piped to "nice" which is way too late ------------------------------------------------------------------------ [2018-01-29 16:21:26] fortwebsolutions at gmail dot com I believe i have solved this, it is not an out right problem with either PHP or apache, rather a process prioritization problem that cane be solved by adding `nice -n -20' before the command to be executed. for the full answer see https://stackoverflow.com/questions/14277910/php-exec-performance/48505455#48505455 ------------------------------------------------------------------------ [2018-01-20 14:35:38] oliver at openbrackets dot net @ spam2 at rhsoft dot net Ok, calm down. The final comment was intended as a "joke", thought that might have been obvious? I know that php's most popular deployment SAPI is still apache, probably. Your usage is 100% opposite from ours. We have multiple own-iron app-servers running the same app for a single domain/app with load balancer in front. So we switched from apache 15yrs ago and never looked back. Hence the joke. The whole php process per webserver process/worker is completely unsuitable for our type of usage, so php-fpm was the obvious choice. Peace and love...enjoy. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
