Are you sure?
I have tried, but nothing changes

[@123.25 ~]# rmmod fuse
[@123.25 ~]# yum install fuse-2.7.3-1.el5.rf dkms-fuse-2.7.3-1.nodist.rf
glusterfs

  Can you try with a different fuse version (kernel module included)?
There have been reports about 2.7.4 performing badly for writes in
certain kernel versions. Can you try 2.7.3 ?
