Azureus is famous for its fsync() behavior, which is known extremely

This is a comment from block_alloc.c:

Hello Edward,
Thank you for explanation. I'm still not convinced though. Cryptcompress
is indeed awesome, but that doesn't change the fact that reserved block
calculation can be improved. 5% of modern 500GB drive is 25GB and I
can't see how that space will ever be used even if I will delete

I agree, reiser4 has been very slow for me, and as I've upgraded the kernel,
it's gotten, if anything, worse.
I'm currently running 2.6.18-mm3. I upgraded (as I have before) in the hope
that the generally very slow issue had been fixed in this kernel release,
and if I knew that it was fixed

It seems the result is: disabled fsync() r4 is even slower than

PFC, thanks for giving us some real data. May I post it to the lkml thread?
In essence, LZO wins the benchmarks, and the code is hard to read. I
guess I have to go with LZO, and encourage people to take a stab at
dethroning it.

Conversely, compression does NOT make sense if:
- You spend a lot of time with the CPU busy and the disk idle.
- You have more than enough disk space.
- Disk space is cheaper than buying enough CPU to handle compression.

Maybe, but Reiser4 is supposed to be a general

The problem is that if we clean this up, we've diverged very much from the
upstream implementation. So taking in fixes and features from upstream
becomes harder

Reiser4 developers, Andrew,
The patch below is so-called reiser4 LZO compression plugin as extracted
from 2.6.18-rc4-mm3.
I think it is an unauditable piece of shit and thus should not enter
mainline.
