Now I've got new question about network abnormal behavior. Strange is according to "Owl router 2" on the schema below of this letter. This box based on Owl-current-20110312-x86_64.iso with compiled kernel from sources by instruction on http://openwall.info/wiki/Owl/kernel-build page. I've compiled network adapters as modules and MPTSAS driver in kernel and other settings have kept as was in Owl. Router 2 has follow components: MotherBoard: Intel S5000VSA Processors: 2xIntel(R) Xeon(R) CPU E5410 Eth1: Intel Corporation 82599EB 10-Gigabit Network Connection [8086:10fb] Eth0: Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) [8086:1010] Strange is according to low speed between client1 and client2 is approx 20-60 Kbytes/s and between Client2 and Router1 speed is 1-2kByte/s. Between routers speed is 46 MBytes/s and between Client1 and Router2 speed is 6-8 MBytes/s. I try all things like offer in articles http://download.intel.com/design/network/applnots/319935.pdf and http://www.redhat.com/promo/summit/2008/downloads/pdf/Thursday/Mark_Wagner.pdf but these changes have not improve situation. However, when I change eth1 adapter on Router 2 to "Intel Corporation 82572EI Gigabit Ethernet Controller (Fiber) [8086:107e]" speed between clients increase to normal level. Schema | Client1 | ----|Eth0 "Owl router1" Eth1 |-------|Eth1 "Owl router2" Eth0 |----|Client2| Have you got any ideas what happen with speed? Oleg Malykh Content of type "text/html" skipped
