Cassandra Lag

Wait, then why is this issue "GMS-exclusive" only?

I don't recall people reporting this issue in KMS forums, nor did I see any complaints in MSEA forum.

*GMS Cassandra causes lag on my old computer, but not MSEA and KMS.

Anyway, GMS client memory usage always make me wonder what are they doing with that much memory.

Running MSEA right now with 78MB memory (stationary), 200~300MB while training. It might shoot up to 400MB in certain bosses but that's it. My GMS client could use up to 800~900 MB.

I think you sort of answered your own question.
The other versions use much less CPU and memory (I presume because GMS is bloated with anti-hack crap).
So maybe being near Cassandra does use more CPU in the other versions, but they are not pushing the limit beforehand, so it makes no noticeable difference.
Similarly, other versions may eat up a lot more memory bossing, but it doesn't cause them problems since they are not already near the limit before they start.
On both my old comp and new, memory usage is around 900M before I even get logged in.
My old comp only has 1.5G total, so I got problems. New comp 8G, no problems.

EditEdit:
The real mystery to me is why does GMS require three times the memory. Are they making multiple copies of everything to help detect hact alterations? Seems really poor coding whatever the reason is.
