Please post your benchmark method.
my benchmark method is by using bbcp.
lustre clients 2.10.5 on RHEL7 are fast (1.1GB/s) while RHEL6 clients
using 2.8.0 perform very poorly (2MB/s)

You can do a quick check with 2.10.5 client by mounting lustre on MDS if you
do not have free node to install 2.10.5 client.
Do you have lnet configured with IB or 10GE? LNet defaults to tcp if not set.
Can it be you are connected through slow management network?

hi, my lnet is configured with both IB and 10GE. it is using IB I
verified it and anyway performance is very slow even if it where just
using tcp on 10GE
since I only get 2MB/s
thanks

Hello,
I have a new Lustre FS version 2.10.5. 18 OSTs 18TB each on 3 OSSes.
I noticed very slow performances couple of MB/sec when RHEL6 Lustre
clients 2.8.0 are writing to the fielsystem.
Could it be a Lustre version problem server vs client ?
I have no errors either on server or client side that can debug it
further...
thanks
Rick
