[lustre-discuss] Large file read performance degradation from multiple OST's

I tried a 2.8 client mounting the 2.9 servers and that showed the expected behavior – increasing performance with increasing OST's.  Two things:

1.  Any pointers to compiling a 2.8 client on recent RHEL 7 kernels would be helpful.  I had to boot into an older kernel to get the above test done.

2. Any help to find the problem in the 2.9 code base would also be helpful.
