What is the Max Concurrent User 2GB can take
My Client runs a Standard VPS Plan from Bluehost 2gb Ram 2core CPU with Wordpress. But over the last few days we have turned a bluehoster, such that I have to reboot the vps at peak of 90-120 user online due to mysql crash. when I run
free -m the free comes down as low as 53. same case last night when there were about 50 users online.
Secondly, I suspected MySQL running the vps out of memory, the database being used for the site was about 67mb and some others unused total about 150mb.
Similar case happen sometimes ago, I have to delete over 2000 post for the VPS to become stable till last week it started again today I have to delete over 2000 post again to get the site running properly. The owner also claimed it was even faster than before.
O yes, I have chatted Bluehost support, it seems like they are a bunch of coffee drinkers doing what I can do by myself [reboot the vps], one told me I have to upgrade ram for 120 Concurrent users.
Enough of my whining,
=> What is the Max Concurrent User 2GB can take
=> What can I do to optimized the site to prevent such occurrence in the future and crashes
=> Am considering installing OpenLiteSpeed as drop-in for Apache on the VPS - is this a good option
