 Looking for some advice on write speed. I currently have my domU's 
installed to 8GB files on a GFS file system. When I create these domU's 
and try to write to them the speed is horrible something that should 
take 10 seconds takes about 2 minutes. Is there any way to speed up the 
write speed for this configuration? Here is what my .cfg file looks like.
    
 
Are the files for your disk  sparse, or fully-allocated ? If they are
sparse, then you should re-create them as fully pre-allocated. Whenever
a sparse disk has to be extended to allocate further blocks performance
is horrific.
