How to test apache.<\/p>\n
Create 2 files:
\ntestload.php
\ntest.php<\/p>\n
Create a php file testload.php that checks the existence of another file named test.php in the same directory of two CentOS 7 servers with the same hardware characteristics and load but with different MPM. One of them will use event and the other one will use prefork.<\/p>\n
<!--?php $filename = 'test.php'; if (file_exists($filename)) { echo "The file $filename exists"; } else { echo "The file $filename does not exist"; } ?-->\n<\/pre>\nWith ab, we will sent 50 (-c 50) concurrent requests at the same time and repeat the test 1000000 times<\/p>\n
# ab -c 50 -n 100000 http:\/\/localhost\/testload.php\n<\/pre>\n200 simultaneous requests until 2000 requests are completed:<\/p>\n
\n# ab -k -c 100 -n 2000 localhost\/testload.php\n\n<\/pre>\nAnother test to localhost
\nPREFORK<\/p>\n
