I don't think that would work since the kernel allocates big memory chunks sort

Hi,
I have Debian installed on two servers, and IBM Netfinity 5000 and an
HP Proliant DL380, and I would like to make the most of their service
ports.
The DL380 has the service port redirected to ttyS0. I can see the the
BIOS boot sequence via minicom, and if I set up GRUB and inittab

Hi,
I am planning on deploying VMware GSX on a Debian system.
While I am happy with ReiserFS for most FS needs, I am wondering if it
would make sense to user XFS or JFS for the VM image partition, as it
seems both perform better with large files.
On a side note, can anyone share information on
It is my understanding that XFS mechanism do a lot of caching to memory
to achieve good performance. This is a consideration between stability
in the case of catastrophy to performance.

2 x PSU, 2 x UPS and a generator should take care of power
XFS is optimized for sequential access performance.
It's work with small files (especially MANY small files) is dismall.
I suggest piloting JFS.

Just to clarify, do you mean batch type processing?

Most of the VM disk files are in the 4-10 GB range, inside there

To answer the why question, its two fold. The first and most impotrant
is the debugging issue. Sometimes problems do not reveal themselves
but for the most stressfull conditions. The second is for experiments
under different conditions to see how it perfoms. i.e. benchmarks.

Yes, indeed. Streaming, mainly video. Worst performance was on

option 3 sounds good. its for debugging and benchmarking.

algorithms and OScaching is useless and it seems I can't use huge
