Checking network card speed

Dear Gurus,

I have two ES40 with 5.1A PK6 clustered with Oracle 9i, up and running..
recently we deployed a new application that requires lots of processing
and bandwith from this servers, and users are complaining that it's very
 slow.. yes, the load is high, but as a system admin I have to check
this, and developers told me that they made all application and database
tunning..

This server is connected to a Cisco Catalysy 3550 with an alt0 network
card. I've read ifconfig, lan_config and alt man pages searching for how
to find the present network card speed without success.. there's
instrucions how to do it, but now how to check the status. Before making
any changes I would like to know the present speed, then I'll try to
reconfigure speed and check the performance again..

Another weird thing. Using Sysman Menu ( Networking (..) Configuring
Ethernet -> Aditional Flags) it don't give me 1000Mbps options, only 10
and 100, is it a 5.1A issue?

I've made a simple file transfer test with sftp and the speed average is
1200 kB/s (the other server is a Windows 2000 Server with Gbit nic
attached to the same switch), it seems very poor to me..


Any help would be nice.
Thanks in advance.
