Playing the VPS lottery.

[rainmotorsports]

So I have been hosting with @WSWD for almost 6 months now, but our original plan was always to host with our gaming provider. The other admins like having everything under one control panel, even if they aren't going to be able to administer the server.

So we figured we would try with 1GB of ram instead of 2 and cut the cost back as well. Only using 190 to 330mb of ram with the current server, though a little mysql configuration to take advantage of more is also in order. Switched from CentOS 6.5 to 7, PHP 5.3 to 5.6 and from MySQL 5.5 to Percona Server 5.6.

The only thing was I noticed it was slower, so I benched it a tiny bit and after checking what CPU we had I knew why. So I played the VPS lottery and moved the machine to another location for a random selection of servers. Got almost the same CPU we have now (Sandy Bridge versus Ivy Bridge).

The switch to PHP 5.6 surely helps a bit. I don't think with the limited ram, current configuration the sql server is all that different. But I had trouble actually installing the mysql bench I was going to use, so I haven't gotten anything but a real world look at it.

It actually seems like the biggest improvement is coming from CentOS7. Here is a test on the same server as you with the exact same specs, only running CentOS7. Noticeable improvement without even upgrading the PHP to 5.6.1.

nope that php script is more cpu dependent for both clock speed (single threaded) and the architecture although there are other factors that can slow it down too (type of virtualization deployed etc)

i.e. Intel Xeon v3 > v2 > v1

this is Xeon E3-1240v3 with CentOS 6.5 64bit with Centmin LEMP stack

this is same clock speed but older generation Xeon E3-1245v2 with CentOS 6.5 64bit with Centmin LEMP stack
