    We have a LAMP cloud based server, hosted at CERA.net, that has been working well for awhile. Now that we"re adding more clients, traffic, volume, etc, the system often crashes when we allow full volume through the system. The core system takes leads in and posts them back out, so we could have 1 post in and as many as 10 posts back out, sequentially or concurrently. I have tweaked apache and mysql here and there but the results never seem to last. We need someone who can optimize our server to handle a heavy load of posts and data.Operating systemCentOS Linux 6.5Kernel and CPULinux 2.6.32-279.14.1.el6.x86_64 on x86_64Processor informationIntel(R) Xeon(R) CPU E5645 @ 2.40GHz, 2 coresReal memory7.68 GB totalVirtual memory1.94 GB totalLocal disk space293.37 GB totalApache 2.2.15MySQL 5.1.73Cisco ASA - IPSEC
