Low FPS on L4D Server *NEW ISSUE*

[BK201]

On server.cfg execution i get

Quote:Unknown command "sv_voicecodec"
Unknown command "sv_voicequality"
Unknown command "mp_chattime"
Unknown command "mp_forcecamera"
Unknown command "decalfrequency"
Unknown command "sv_allowupload"
Unknown command "sv_allowdownload"
Unknown command "sv_maxupdaterate"
Unknown command "sv_minupdaterate"
Unknown command "sv_instancebaselines"
Unknown command "sv_maxunlag"
Unknown command "sv_unlag"

All of which are in the server.cfg, some more important than others. How am I supposed to control bandwidth without these?
