[lc-devel] linuxcompressed on a 2.4.x software RAID (md) enabled system ?

[Olivier K. <ka...@ka...>]

Hi,


 	I'm really interested in linux compressed, as my current
system is really slow when it comes to I/O access;

 	3x180Go IDE Disks, unfortunatelly they stand on
two IDE channels.

 	Using "du -sk *" on a 110Go partition is slow and takes no more 
than 20% CPU. Launching the same command a second time is not faster, 
which makes me think that some caching or cache compression technique 
would be able to improve things.

 	I have 386Mo RAM, 1Go swap, no special tunning as of now. 
Unfortunatelly, running 2.4.27, I'm unable to find the 
/proc/sys/vm/buffermem file which would have allowed me to tune I/O 
buffers.

 	Do you think that compressed linux could improve performance in my 
case ? (I think that low ram is one of my problems, even if I don't have 
more than X running)

 	I tried to apply the latest patch (for 2.4.18) to 2.4.27, but some 
work needs to be done, as little things seem to have changed in the code. 
(about 7 rejects, not obvious to patch by hand)


 	any comments very welcome !
