Subject: tbench regression on each kernel release from 2.6.22 -> 2.6.28
Date: Mon, 11 Aug 2008 13:36:38 -0500 [thread overview]
Message-ID: <48A086B6.2000901@linux-foundation.org> (raw)
It seems that the network stack becomes slower over time? Here is a list of
tbench results with various kernel versions:
2.6.22 3207.77 mb/sec
2.6.24 3185.66
2.6.25 2848.83
2.6.26 2706.09
2.6.27(rc2) 2571.03
And linux-next is:
2.6.28(l-next) 2568.74
It shows that there is still have work to be done on linux-next. Too close to
upstream in performance.
Note the KT event between 2.6.24 and 2.6.25. Why is that?
