Though I could not exactly understand what you wanted to say (may be cause English might not be your native language) but What I could understand is that
'You want to increase your fps on server which currently runs at 67 fps'.
If I'm right then In order to increase you fps:
If running Linux:
Simply put
fps_max 1001 and
sys_ticrate 1000 in your
server.cfg
If running Windows:
Use the Simple metamod Plugin attached herewith.
Put
sys_ticrate 1000 in your
server.cfg
