VPS Specs and Qualifications

So, My server has been maxing out every night, and last night we just had our second “not enough allocated memory” and “Major VPS Lag detected!” From TxAdmin, crashing the server. My co owner wants to switch to the High memory $30 dollar option that has 1 CPU and 24 Ram from Linode, but I want to switch to the 4 CPU and 8 Ram from Linode. I oppose because I think that CPU is important, and dowgrading it from 4 GB (current) to 1 GB CPU will not only limit the Ram, but also slow the server down, but I’m not so sure. Would CPU be important?

PS: Yes, I know, This also may be caused by too many un-optimized scripts. Which brings me to a side question becuase I haven’t even touched scripts: Is jamming in like 8 scripts into 1 bad? Or even 20 scripts into 1? Same for vehicles. Is there a limit in which it would be unacceptable?

Thank you guys for helping me learn :smiley:
