- GENERAL
- INFORMATION: A customer had a SystemPro with two EISA (Compaq/Proteon)
- Token-Ring adapters running NetWare 286 v2.15c. He was
- running an Oracle database application and it was running
- very slowly. He sold the customer another Token-Ring
- adapter thinking that he would get better response with
- fewer users on each ring (he had only 70 users total).
-
- He installed the adapter and the response was even slower.
- At first we thought it was Service Processes, but he had
- three available. What was actually happening was the EISA
- Token-Ring adapters, when running NetWare 286, run in a
- translation 16 bit mode. This, combined with the bus
- mastering, was slowing things down.
-
- We recommended they put one EISA Token-Ring adapter in the
- file server and run it at 16Mb with NetWare 386. That way
- the adapter would be running in 32 bit mode instead of 16
- bit mode and bus mastering would be using the EISA
- specification instead of the slower ISA specification.
