Hello!
We are observing severe IPv4 forwarding degradation
when switching from sk98lin to sky2 driver. Setup:
plain 2.6.21.3 kernel, 88E8053 Marvell Yukon2 MAC,
sk98lin is @8.41.2.3 coming from FC6, SKY2 driver from
2.6.21.3 kernel.
Benchmarks are done using bidirectional traffic
generated by IXIA, sending 256-byte packets. Observed
packet throughput is almost 30% higher with sklin98
driver.
Ethernet flow control is turned off in SKY2 driver
(hard-coded as off, we know about this problem).
I also have oprofile records of the drivers in case
anybody is interested.
Please share info if you know anything on SKY2
performance bottlenecks.
Thanks in advance,
Philip R.
