Descriptive Problem Summary:

So, I am not even sure if this is even the right place, given its not really a *bug*, but its still worth bringing up.

I wrote BYONDBench (https://github.com/AffectedArc07/BYONDBench) a while back for the ability to pick SS13 server hosting hardware, and noticed some interesting things.

The main things to point out here are
- File IO is faster on linux, especially for large writes
- List operations tend to be a lot slower on linux (NOTE: Some people get the results to be on par, I however cannot)
- JSON decode is incredibly faster on linux (2.6 seconds as opposed to 29.6 seconds)

Numbered Steps to Reproduce Problem:

1. Run the above benchmark. It will freeze DD, dont worry about it
2. Compare results over different OSs on the same hardware

Expected Results:
The OSs to behave pretty much the same

Actual Results:
See above

Does the problem occur:
Every time? Or how often? Yes
In other games? No, its specialised
In other user accounts? Yes
On other computers? Yes and no (Some people get much faster list times on linux)

When does the problem NOT occur?

No idea

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)

Unsure, will do on request

Workarounds:
I have no idea
