using 2007-06-01 gluster tla 2.4mainline, linux 2.6.15 and 2.6.20, fuse
2.6.5
If I have a single large copy going to the glusterfs volume the speed
can peak at 11MB/s which is ok. When I do just a 'du -sh /mnt/glusterfs'
while the transfer is happening then the transfer falls to about 300kB/s
until the du is done. Same when I run an rsync and it only is comparing
the files (hasnt started transferred yet).
Curious why a copy would slow down so much.
gluster-*.conf files below. For the client conf I was using the unify
example from the wiki with same results. Tried with the writebehind and
iothreads with same results as well.
Thanks in advance,
Dale
