SERVER LAG issue

lads i need some help in regards to an issue i have been having server sided. Just for context: I used to own a server, when i shut down i created a backup of all its assets and stored it in my pc. i made another server, added assets for it then shut it down. I then re-added the backup i had to reopen the first server i made. everything was fine, no lag no nothing. We then added an Add-on EUP pack (extra slots) with vests, tops, pants etc. was good for 1 day then the server started lagging like crazy, fps drops, no spawning guns and eup not loading. I removed the pack and the problem still persisted. I then # all resources in the cfg obviously keeping the essentials and the problem still occurs. I have no idea how to fix and i need help.
