Server TPS dropping (Skyblock style server)

Hi, I am running a server that is a skyblock ish style server with roughly 60-100 players on at a time. However the server experiences HUGE TPS and MPTS drops sometimes to as low from 4TPS. I have tried optimising and upgrading RAM etc but the only thing I think can be affecting this is chunks loaded. I have tried optimisation in server settings but any idea what I can do to help with this is what to upgrade. Thanks
