Thanks for this update - One of the items I see in the 1.6.18 Release Notes

* Support for mainline kernel 4.4 and distribution kernels with
       backports from it, alas at a performance penalty (12226 12227 12228)
       (RT #132677 #132819)

I've heard that the performance penalty here is roughly 50% - Is this correct?

I've also heard that this is fixed in the Auristor client - Is this correct?


Thanks,

Rich
