Hi @Bladerunner!
One reason for the large amount of memory used could be that the plugins are loaded anyway, even if no patches are loaded in the plugin. The large number of loaded plugins could explain at least in part the memory usage.
To check if this is indeed the case, you could try to put a few plugins in “Unloaded” status (let’s say 1 out of 10, about 20 in your case), which is the only way to remove them from memory according to these thread:
If memory occupation decreases by about 10% (assuming for now, that the unloaded plugins have the same average memory usage of all the others) then the loaded plugins are the main culprit for your large memory usage.
Others more expert than me could probably give better advice.
