[Lustre-discuss] Performance Regression in 1.6.5 ?

[Roger Spellman]

I'm seeing a performance regression for Writes in 1.6.5 relative to
1.6.4.3.  However, I'm also seeing a performance improvement for reads.
I'm running over Mellanox IB fabric.  Is anyone else seeing this? 

 

Here are some numbers for my HW:

 

1.6.4.3 + ofed 1.3:    Writes 390 MB/s,  Reads 369 MB/s

1.6.5   + ofed 1.3.1:  Writes 366 MB/s,  Reads 437 MB/s

 

Has anyone else taken performance measurements?
