Re: Network card speed
I use this trick to determine the real speed of any connection: On guest 192.168.0.2: nc -l > /dev/null (on some distros, nc is called netcat, so check if it's installed) On guest 192.168.0.3: dd if=/dev/zero bs=1M count=64 | nc 192.168.0.2 This will dump 64MB of zeros over the network and show the speed after it. Try this between your guests on the same guest lan, and with a guest and an external host.

Re: Network card speed
Victor, The output you included showed that Linux thinks this is Guestlan QDIO connection. I always thought that between the Linux guests and the VSWITCH, you used the QDIO protocol. And from the SHARE presentations that I have attended, that if you have settings like correct MTU sizes, that this protocol is very fast. (I don't have a presentation handy at the moment, but it think I remember that the speed that this protocol can operate at is much faster than the OSA adapter can send it out over the wire.)

Re: Verify network card speed
wow - I just used OSA/SF - what a strange interface. But I guess if I got used to RACF - Anyway OSA/SF does what you want. As Alan also indicated you can get this info from the HMC, I did that, too. I guess I prefer using OSA/SF. I did function 12, 4, 13 (start managing, get configuration, stop managing) in OSADMIN1 via IOACMD EXEC. I will maybe (or not) play with the GUI. But then again I don't like GUIs in the mainframe environs. So you need CMS and OSA/SF do to this. I can't think of a way to get this info in a linux virtual machine, unless the card_type file when it returns OSD_xxx where x = 100 (I've seen that) means something. A simple NETSTAT query interface would be nice. But at least you can get the info.
