another trivial comparison was the special 4mbit t/r (16bit bus) card done for the pc/rt and the 16mbit t/r (32bit microchannel) card used by the rs/6000.
the 4mbit t/r card had been specially designed pc/rt card for maximum thruput. the 16mbit t/r card used by the rs/6000 was the same as what was used for ps2. the ps2 lan environment had design point of SAA and terminal emulation paradigm (trying to stick the client/server genii back into the bottle) http://www.garlic.com/~lynn/subnetwork.html#emulation it turned out that the pc/rt 4mbit t/r card had higher per card thruput than the 16mbit t/r card used by the rs/6000. another comparison was that the new almaden research building had been wired for cat5 (16mbit t/r) ... however, when they went to deploy ... they found that 10mbit star-wired enet (over cat5) had higher per card thruput, higher aggregate network thruput, and lower latency ... than running the same wiring with 16mbit t/r. it was during this period that we came up with 3tier architecture, middle-layer, etc http://www.garlic.com/~lynn/subtopic.html#3tier and out pitching it in customer executive presentations. it included lots of enet content ... and we were taking hits from the t/r factions (i.e. because of enet content) and saa factions (because we were not only not terminal emulation paradigm ... but moving past client/server to 3tier). misc. 801, romp, pc/rt, rios, power, rs/6000, fort knox, etc ... postings. http://www.garlic.com/~lynn/subtopic.html#801 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
