Reiser vs etx4

[Alfredo Rezinovsky <alfredo@xxxxxxxxxxxxxxxx>]

In the page reccomends reiserfs. So I tried to set up a squid for 
200Mbps squid using reiser and squid 3.3

I had a problem, every five to ten minutes, the system freezes and the 
bandwith drops to a half for about 10 seconds.

I tried tuning squid in many ways. And I noticed reiser flushes the 
buffers all at a time, freezing the I/O, I suppose even the network I/O. 
The solution was to reformart the cache disks using ext4 (noatime an 
so). Now the proxy runs smoothly.

I know there should be a reason for recomending reiser in the 1st place 
but I had very bad experience with it.

Also... I know people leaving linux in favor of BSD to be able to use 
zfs. Anyone knows the status and usability of zfs in linux ?
