This is the current state: I could finally compile the current CVS kernel + the Cobalt patches from http://www.colonel-panic.org/cobalt-mips/ The Raq2 is now running 2.6.7-rc3. With this upgrade everything got bettter, but it's still not perfect. With the standard Debian ftpd connections begin with about 2.5MB/s, but then drop to 1.37MB/s. Using vsftpd it's similar, but the transfer rate doesn't drop so much. I can get about 1.67MB/s. There is no real difference whether firewalling/masquerading is used at the same time or not. I'm just a bit confused because I was told by another Raq2 owner that he could get transfer rates of about 6 or 7MB/s using the current CVS kernel. I did all my tests by transferring the ungzipped gcc-3.4.0 tarball. That's 182MB. The nice thing is that I can now transfer a big file via ftp without killing the whole machine. With 2.4.26 beginning an ftp transfer made all other connections unuseable. Outgoing SSH connections dropped down so much that I could wait for every typed character to appear. Maybe it's a good idea to file a Debian bug report. Their standard kernel seems to be problematic. Anyway, the network problems didn't go away completely. I had one "almost" network freeze with the new kernel resulting in lots of dropped packages and transfer rates similar to what I described in my first mail. Restarting the network solved this. tessa:~# ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:10:E0:00:31:F5 inet addr:192.168.2.10 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::210:e0ff:fe00:31f5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4314429 errors:2 dropped:10412 overruns:0 frame:5 TX packets:3013429 errors:23 dropped:0 overruns:4 carrier:19 collisions:0 txqueuelen:1000 RX bytes:1151870219 (1.0 GiB) TX bytes:1305479776 (1.2 GiB) Interrupt:19 My current setup is like this: I have connected eth0 to a 100Mbit switch and eth1 to a gateway router via 10MBit. The box has about 1 day uptime now and works stable at the moment. I'm waiting for the next network freeze... ANother thing worth noting is that after upgrading to 2.6.7-rc3 I have the same problem with "df" that was described on this list before: tessa:~# df Filesystem 1K-blocks Used Available Use% Mounted on df: `/': Invalid argument df: `/proc': Invalid argument df: `/sys': Invalid argument df: `/dev/pts': Invalid argument df: `/dev/shm': Invalid argument df: `/boot': Invalid argument df: `/export': Invalid argument strace gives the same info as it was described in the past. All in all, I'm very interested in any possible improvement. I need a low cost server that is silent enough that I can sleep in the same room and this Cobalt seems like a very good candidate (after replacing the small fan of course). thanks for your help. mfg Dennis P.S. I'm not on the list. I'm reading this list via a web-gateway. -- de-moc-ra-cy (di mok' ra see) n. Three wolves and a sheep voting on what's for dinner.
