Cyrus - GFS slow start and poor performace

[Scott Likens]

If you wish to do load balancing,

I suggest looking at nginx.

For documentation ... http://wiki.codemongers.com/Main

I don't have a lot of experience with GFS1 or OCFS, however I don't  
expect great performance.  I would imagine worse then ext3 or about  
the same is the best you will be able to achieve.

You may have better luck with syncclient, or setting up Murder with 2  
Front ends and 1 backend.  I guess the bottom line is read-write  
configuration shared between 2 servers is .. (to me) hit and miss.  It  
really depends on what your trying to do with it, and how your trying  
to make it work.

In this case, I would not personally suggest a read-write with DRBD or  
ocfs/gfs as you are going to either encounter bugs from filesystems,  
cyrus, or both; if someone has a configuration where any 3 of those I  
just mentioned works great... then by all means please chime in.
