When we try to send long text post with over 2000000 characters to FreeBSD server we got a long running request With the number of characters the processing time substantially increases as can be seen below in the tests that we carried out: with 2000000 characters the time is as follows: FreeBSD - 2,5s Ubuntu/Linux - 64ms with 10000000 characters the time is as follows: FreeBSD - 50,71s Ubuntu/Linux - 100ms Please note that we used Apache 2.4 and PHP with the same configurations on the servers. The problem was not present in the previous PHP 5.4 on FreeBSD.
