High Memory Usage and Slow Startup on Linux #35

Open ForLoveOfCats opened 6 years ago

ForLoveOfCats commented 6 years ago

OS: Manjaro GNU/Linux x64 w/ Plasma 5 TUNG Version: 0.2.4 Mods or Addons: None

TUNG uses 1.29 Gigabytes of RAM sitting on the main menu. This causes excessive swapping on system with smaller amounts of RAM. Perhaps the long game startup time on Linux is related to this?

Cheers!

785 MB on main menu for me on Ubuntu 16.04, compared to about 200 MB on Windows.

0.2.5 now uses between 2.7 to 3 gigs of ram on a relatively simple world. In addition to this it fires up over 50 threads (Is this normal?). World download below.

No. Crap. I screwed up, 0.2.5's new system for colored component pieces is sucking up threads waaaaay more than it needs to. Looks like I'm doing a 0.2.6.

This is absolutely baffling. I too am getting memory usage that's too high, but when I profile the game it tells me that <200MB are being used, so there's no way to tell where all that extra memory is going.

This comment is intended to correct information stated earlier as well as add information already discussed via other communication methods.

It has been determined that the performance drop in 0.2.5 was not related to high memory usage. Instead it was a cross-platform issue regarding GPU utilization.
It has been determined that the high thread count (50+) appears to be normal and having no ill effects to overall performance.
0.2.6 has lowered RAM usage on Linux slightly but is still rather high.

I have determined that the high memory usage is not caused by a memory leak as the absurdly high memory usage is allocated on game boot up and all actions taking place after that point do not raise memory usage significantly.
