gmod srcds sv_lan 1 server internet lag

[gamemann]

Hell everyone. I setted up a gmod server for srcds on the same machine i am on. Reason i did it is because on a listen server some of the mods crash my pc... Then i made a srcds gmod server(setted it for 1 of my 4 cores, and ran gmod.exe(hl2.exe) on the other 3 cores) so basically my server gets best performance so i was lag free for fps issues then i ran into another problem -.-
Internet lag, my choke is 80 when i kill an npc, rate is 323023.
So yeah i want it to not use internet lag XD was hoping sv_lan 1 would do that.... Is there any possible way to make it so it doesn't use internet? There is probably no way but doesn't hurt to ask XD

pc specs:
processor: intel i5 2500K @ 3.3 ghz(4 cores)
ram: 8 gb
operating system: windows 7
upload speed: 3.60 mbps
download speed: 25 mbps


MORE DETAILS:
Okay only mod installed is gibmod!
Uh, here is command line:

Code:

@echo off
cls
echo Protecting srcds from crashes...
echo If you want to close srcds and this script, close the srcds window and type Y depending on your language followed by Enter.
title GFL Test Server
:srcds
echo (%time%) srcds started.
start /wait C:\SRCDS2\Server\gmod_server\orangebox\srcds.exe -console -game garrysmod +maxplayers 100 +port 27015 +high +exec "server.cfg" +map gm_construct
echo (%time%) WARNING: srcds closed or crashed, restarting.
goto srcds

Here is the server.cfg:

Code:

host_threadmode 2
sv_maxrate 0
sv_minrate 0
sv_lan 1
hostname "Roy's server"
sbox_maxnpcs 3000
sbox_maxragdolls 3000
sbox_maxprops 30000000

thanks,

A server doesn't saturate your connection enough when its empty to give you any of those issues. Also, this is why you shouldn't run a server on the same computer you play on
