[Gluster-users] Gluster performance on the small files

[ML mail]

For those interested here are the results of my tests using Gluster 3.5.2. Nothing much better here neither...

 Hi,
I have seen the gluster performance is dead slow on the small files...even i am using the SSD....it's too bad performance....even i am getting better performance in my SAN with normal SATA disk...
I am using distributed replicated glusterfs with replica count=2...i have all SSD disks on the brick...
