[Gc-linux-devel] Compressed VM

[Dead2 <de...@ci...>]

Just wanted to point out the possibility of running
"linuxcompressed". First and foremost this would
benefit us by making the swap compressed.
Secondly it can also compress parts of the main
memory.

It is developed fro the i386 platform, but is also
reported to be working (at least swap part) fully
on other archs. It does not contain much i386
specific code, that's just what the developers use.

On the GC, if this could take our 16MB swap to
effectively be 20-50MB (depending on contents),
it would surely mean a world of difference.

The memory part is a bit different. You have to
specify how much of the memory is to be
compressed. 50/50 is usually a good start.
So, 12MB compressed ram would probably be
able to contain 20-30MB too, without beeing
overly optimistic. (24-48 is what I'm thinking)

So, in effect this would enable us to atleast double
the memory load on the GC..  And that is a very
nice increase on such a memory starved box.
