Plutonium

since a couple of days people experience lag spike on my server idk what to do i tried making a fresh install of the server, reinstalling windows and people still get lag spike from time to time my internet is really good like when im downloading its at 100mb/s + people on my serv dont get high ping neither it just lag every 2 to 5 min or so idk what to do plz tell me u guys expereience something simiar and found a fix

in fact the more im trying to play multiple map the more im realizing i just dont know where to find the maps name if someone could teach me where it can be found i would really apreciate it !!

i host a server where i play custom maps with my friend but i cant seems to amke requiem run it always says that the name i gave to the map is wrong let me show u my config rq :

set sv_mapRotation "map nazi_zombie_prototype map nazi_zombie_asylum map nazi_zombie_sumpf map nazi_zombie_factory map sanatorium map ugx_requiem"

set sv_maprotationcurrent " map ugx_Requiem"

i tried many name combination like : ugx requiem (without underscore) , only requiem , only ugx and ugxrequiem and it didnt worked so if any of u guys know whats the map name it would be reallly cool !!!
