gjournal for hosting server

[Artem Kuchin]

Hello!

I am setting up a new hosting server which will host about 100 sites and 
mysql databases for them.

I've read about gjournal and as i see the following benefits:

1) NO fsck after crash
2) 2x speed for small files writes
3) Some extra speed for small files reads (why???)

The web servers are mostly serving tons of small files and do tons of 
small writes.
I thinks the all in all with gjournal the fs speed should be higher.

Any thoughts?

Artem
