Greetings,
I am experiencing a very significant network throuput problem with
VMWare Server 1.0.0 build 24927. Both my host and guest OS's are 64
bit Suse Linux 10.1. I am using iperf version 2.0.2
(http://dast.nlanr.net/Projects/Iperf/) to messure the IP/Network
throughput. The numbers I get are as follows:
guest to host - 73 Mbits / sec
host to guest - 113 Kbits / sec
Yes, that's Mega and Kilo. That means it is 646 TIMES faster from
guest to host than host to guest.
I checked all the things I could given my limited understanding.
There doesn't appear to be any network errors going on.
I have three physical network ports and I am using and mapped to two
of them on both the host and guest OS. Yes, the VMWare tools are
installed on the guest OS.
The guest OS is configured as follows:
Ethernet 1 - Custom /dev/vmnet2
Ethernet 2 - Custom /dev/vmnet3
Except for the drastic speed problem everything is working.
The ipconfig on the host is as follows:

The boot log for the host are filled with comments about the eth ports
which I don't understand. I can e-mail it if necessary. The same id
true for the guest OS.
Your help is greatly appreciated.
