Server FPS plummeting?

[Flapadar]

Quite frequently, server FPS drops to around 10 (From ~250) and hangs around there. Normally during a lot of player activity. The server is 28 slots - Garry's Mod (Running Fretta).

Server specs:



Windows Server 2008 R2 (x64)

Code:

21:15:34 CPU   In    Out   Uptime  Users   FPS    Players
         102.06 102439.42 413268.13    1702    55   11.70      26

Rates + stuff

Code:

sv_minupdaterate 66
sv_maxupdaterate 66

sv_mincmdrate 66
sv_maxcmdrate 66

sv_minrate 150000
sv_maxrate 150000

sv_use_steam_voice 0

Tickrate default (66?)


Server IP: 188.165.193.84:27026 - incase anyone needs to see what I mean to tell me more about it.
