Howdy, I bought a Sony Vaio FX210 about two weeks ago, and have been having some issues with it being *really* slow on my network. It has a built-in rl0 (yes, I know that chipset sucks), and I also have a D-Link DFE-650 pccard. I get the same results with both interfaces... extreme slowness. Here's an example: Fetching mozilla from a desktop on my network... # make fetch >> mozilla-source-0.9.tar.bz2 doesn't seem to exist in /usr/ports/distfiles/. >> Attempting to fetch from ftp://ftp.mozilla.org/pub/mozilla/releases/mozilla0.9/src/. Receiving mozilla-source-0.9.tar.bz2 (25066194 bytes): 30%^C 7567624 bytes transferred in 49.6 seconds (149.13 kBps) fetch: transfer interrupted # Fetching mozilla from the laptop... # make fetch >> mozilla-source-0.9.tar.bz2 doesn't seem to exist in /usr/ports/distfiles/. >> Attempting to fetch from ftp://ftp.mozilla.org/pub/mozilla/releases/mozilla0.9/src/. Receiving mozilla-source-0.9.tar.bz2 (25066194 bytes): 30%^C 7545400 bytes transferred in 482.1 seconds (15.29 kBps) fetch: transfer interrupted # The difference is quite a bit, and extremely noticable. Both machines are plugged into the same hub (a 10/100 NetGear -- yes, I know, I need to go buy a switch). Here's the ifconfig output for xl0 on the desktop... # ifconfig xl0 xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.1.4 netmask 0xffffff00 broadcast 192.168.1.255 ether 00:10:4b:0f:d1:3e media: autoselect (10baseT/UTP) status: active supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback> # And here's the output for rl0 on the desktop... # ifconfig rl0 rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255 ether 08:00:46:1c:d9:c8 media: 10baseT/UTP <full-duplex> status: active supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback> # The performance from the D-Link card on the laptop is about the same as the built-in rl0. I'm totally confused as to why this is happening. I know the RealTek stuff sucks, but I can't imagine it sucks so much that I'd see over 100kBps difference between the two. I've tried swapping ethernet cables, and had the same result. Anybody have an idea what's going on here? - jim -- - jim mock <jim@compete.com> www.compete.com - jim@FreeBSD.org - - senior systems administrator - Compete, Inc. - ph: 1.617.867.7035 - To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
