Open Server 5.02 from SCO supports IBM 9595 machines right out of the box. That makes installation straightforward and easy. Drivers are part of the SCO Advanced Hardware Supplement (AHS) Release 5.2.0. In addition version 1.1.1 of NETIO has an executable file for SCO Open Server included.
EnvironmentDIME will be tested against Talent again. The only
difference is, that an other IBM 1GB hard disk, which holds SCO Open
Desktop, is working now inside DIME together with the IBM
Auto LANStreamer MC 32.
There seems to be no adjustment for the TCP
Receive Window Size (RWIN) and no Full Duplex driver support under SCO
Open Server. Maximum Transmission Unit (MTU) is set to 4044 byte by
default.
SCO command sar -u 2 30 is used to measure CPU Load
for the NETIO executable. Just like before, all test runs were done
ten times and averaged.

IBM's Auto LANStreamer MC 32 with FRU 60G1593 works in the MCA based IBM RISC workstations. The 42W is equipped with a 120MHz PowerPC 604 cpu, 512KB second level cache, 96MB RAM, POWER Gt4xi 24-bit Graphics Subsystem and an IBM DDRS-34560 4,5GB hard disk. Operating system is IBM's proprietary Unix, called AIX, here with the version 4.3.3. JANUS is the workstation's host name.
EnvironmentJANUS will be tested against Talent. Full Duplex
support is turned on. Maximum Transmission Unit (MTU) is set to 1498 byte by
default.
AIX command sar -P ALL 12 6 is used to measure CPU Load
for the NETIO executable,
which was compiled from the NETIO 1.3.1. source
with gcc 3.4.3. Just like before, all test runs were done
ten times and averaged.

The 42W has enough power to operate the Auto LANStreamer's 32Mb/s bandwith. CPU load never exceeds 29%, which means continuously high data troughput with continuously low CPU load. HTTP loads appear to be nice quick. The whole machine acts very responsive.
