"Gentlemen,
FYI...
Update to the January 13 report, includes PC MACLAN and 1000Mbps Gigabit tests,
along with a comment about Mac OS 9.1 network tests. Posted to the ASTEC BBS.

Connecting via what network speed and network protocol, results in
what kind of real world file transfer speeds?

Network Protocol Read Write Notes
(KBytes/sec)
10Mbps AppleTalk/7.6 759 593 Quadra 700 50MHz 68040 (historic ref)
10Mbps ASIP 6.3.2/AT 817 713
10Mbps Snap! TCP 997 953
10Mbps ASIP 6.3.2/TCP 1033 1098 Approx. 9Mbps
100Mbps Snap! AppleTalk 1654 1072 Snap! Server 1000 via AppleTalk
100Mbps File Share/TCP 1919 980 OS 9.0.4 File Sharing via TCP/IP
100Mbps File Share/AT 2187 2261 OS 9.0.4 File Sharing via AppleTalk
100Mbps Snap! TCP 2885 2812 Snap! Server 1000 via TCP/IP
100Mbps PC MACLAN/AT 2919 1788 PC MACLAN on NT 4.0 (Dell 266/P2)
100Mbps ASIP 6.3.2/AT 3719 1852 Overly slow write rate (?)
100Mbps ASIP 6.3.2/TCP 8582 8326 Approx. 70Mbps
1000Mbps OS X Server/TCP 35128 31110 Approx. 274Mbps (data from 3rd
party, not from ASTEC. Units involved G4 450MHz and AsantÈ Gigabit Switch.
Speed is less than 30% of advertised Gigabit speed of 1000Mbps. Few
installations are known to actually reach much above 350Mbps at this point
in the Mac/Gigabit's young history. As a point of reference, we have tested
Windows NT 4.0 Gigabit on a 4-CPU 833MHz Server at 460Mbps)
Mac OS 9.1 Note - The above 10/100Mbps tests were also run using freshly
created boot volumes from the Apple OS 9.1 retail CD (M8081LL/A) and no
differences in file transfer speeds were noted when compared to the Mac
OS 9.0.4 tests, above.
All Read and Write tests (except 1000Mbps Gigabit) run with shared
volume mounted on 640MB B&W G3 450 and tested with Helios LanTest
2.5.2, available
at:
www.helios.de/helios_P/LanTest.html
The ASIP Server is a 768MB B&W G3 450 running OS 9.0.4 and ASIP
6.3.2. Ethernet is via NETGEAR FS308 100Mbps Switch, with a NETGEAR
EN104 10Mbps hub for 10Mbps tests. A Beige (Rev.3) 500MHz 384MB G3
was used for 10 and 100Mbps AppleTalk File Sharing tests, using both
its built-in 10Mbps Ethernet and a ZYNX 345 10/100Mbps Ethernet NIC
using the Apple Enet driver. All Macs are running OS 9.0.4 plus
updates.
The "Snap!" is a Quantum Snap! Server 1000, running current firmware.

2nd Opinion on Snap Servers: On 1/19/2001 Rick Pepper sent his comments defending Snap Servers and noting better performance in models above the low end 1000 model used by Rod.
