8gb of ram
2tb hd
i5 dual core 3.1GHz processor
100mb of bandwidth


well for a start you have options-
for faster page loads get ssd hd for .3 second imporvement
second is to upgrade your port to a 1000mb / 1 gig

also depends on your control panel setup, plesk ,cpanel,ispconfig,directadmin
it may need a tweak

for the specs you have id say your servers bit small for the needs if you have major activity on your site many torrents active connection, active users
depending on your budget-
ovh has same server for 29.99
i would suggest maybe something like this
