Hi I told to a friend about Centminmod and he is ready to move to it I told him the best for you George and for Centminmod ! He has about 10 sites at cpanel at the moment using Apache 2.2.23 and PHP 5.3.20 using PHP 5 Handler fcgi and Apache suEXEC on. Yesterday i help him with a semaphore limit ..... On busy times he has about 14.000 connections on the main site and the rest 9 sites total they have about 1.000 connections only all together. Checked using: netstat -n | grep :80 |wc -l So he is ready to move to a new very HUGE dedicated server next week Centminmod In my opinion he is not need so big server but if he want it no problem for me CPU: Intel Xeon 2x E5-2650v2 16c/32t 2,6 GHz+/3,4 GHz+ RAM: 128 GB DDR3 ECC 1600MHz Disks: 3 x 480 GB SSD Intel DC S3500 SATA3 6 GbpsHardRAID+ LSI 9271-4i FastPath - RAID 5 free IPs* 256 IPs Public network card: 1x 1 Gbps So what do you think i must be take care for such case so i can have the success story and advertise you on his forum also with more than 500.000 users? I am thinking to increase some kernel limits like open files and a few more and to use for php-fpm the dynamic option plus APC and Memcache. Please advice Thanks !!!
