Subject: SKY2 vs SK98LIN performance on 88E8053 MAC
Date: Fri, 8 Jun 2007 13:41:55 -0700 (PDT) [thread overview]
Message-ID: <884143.12109.qm@web52311.mail.re2.yahoo.com> (raw)
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 @revision 8.41.2.3 coming from FC6, SKY2
driver from 2.6.21.3 kernel, both drivers are in NAPI
mode.
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.
