you can delete command +servercfg and make gamemode_deathmatch_server.cfg only,and there put cvars. If you use deathmatch it will execute gamemode_deathmatch.cfg first automatically,then gamemode_deathmatch_server.cfg right after that on every mapchange.
Add one more cvar in gamemode_deathmatch_server.cfg after bot_quota : bota_quota_mode fill
Threaded Mode
