My experience has shown that disabling even a lot of services makes negligible difference in performance, while considerable risks are hidden behind inter-dependencies. Consequently, my advice is to leave services alone, and seek other more effective and safer ways to increase system performance.
OP needs to say his goals: performance or security, in the first place. However, I agree. For performance he could go the hardware route, it requires $$ though.
well in my modest opinion first you need good knowledge in services.msc, although in gpedit.msc (if using PRO or Enterprise versions) can explain in more details severals items related so using reasoning you decide; in contrary don't make changes
Adding more (hardware) memory is highly effective, but much can be achieved without hardware upgrades. Examples are: Defragment (not SSD), update drivers, uninstall programs not used, replace those used with lighter ones, stop apps from unnecessarily starting with the system, reduce gimmicks & visual effects, avoid browser addons, etc.
