I'm not the IT director. How can I find this out?


I got this from CPanel/WHM: (i do have root access)
 
Total server memory:
Memory: 74216004k/76546048k available (5468k kernel code, 1049156k absent, 1280888k reserved, 6953k data, 1316k init)

20 GiB



... Also, some more Info:
CENTOS 6.9 x86_64

Not sure if you just want to remove the match()'s in the WHERE clause or in the ORDER BY clause too, so I did both ways:
