I think this should be a very good idea. I have tested it on a old
Pentium 3 with 512 MO of RAM and it works really better on heavy RAM
usage.
I used 30 % of the local RAM to swap on with a high priority, and 512 Mo
of HDD Good old Swap partition with a low swap priority and it seems to

We should pack this utility. Debian begins to package it (not available
yet, but probably soon)

And the new version has a rzscontrol utility to control the ramzdisks.
As suggested by the author of ramzswap it would be better to make this a
package which can easily be upgraded and include rzscontrol and man pages.

Note: lucid appears to be using an obsolete version (0.5.3) of compcache:

This is still an issue. I see that COMPCACHE is enabled in my lucid kernel:
$ grep COMPCACHE config-2.6.32-16-generic
CONFIG_BLK_DEV_COMPCACHE=m
# CONFIG_BLK_DEV_COMPCACHE_DEBUG is not set
# CONFIG_BLK_DEV_COMPCACHE_STATS is not set
The module name now is ramzswap. Probing it creates /dev/ramzswa
Lucid comes with the compcache module (ramzswap) but never uses it. As
indicated in the description, if Ubuntu conditionally enabled compcache,
low memory systems would benefit (such as embedded devices and
netbooks). Since this behavior has not been changed, the bug is still
valid.

Hi Craig,
Please be sure to confirm this issue exists with the latest development
release of Ubuntu. ISO CD images are available from
http://cdimage.ubuntu.com/releases/ . If the issue remains, please run
the following command from a Terminal

With 2.6.33 compcache is now shipped in the staging area, for Lucid+1 or
whenever the .33+ switch is made this would at least remove the
requirement to patch the kernel. Upstream also seems to have solved the
scalability issue on multicore.

It should atleast be considerably easier to add, maybe as an option in
the install menu or something, that's enabled on systems with 1gb memory
or less. Even on a system with 4gb memory compcache helps performance
considerably (allowing io cache to function optimally without swapping
