- PROBLEM: A customer reported extremely slow performance on his
- NetWare Access Server when running his customized order
- entry software. The symptom was that screen information on
- his remote PC using the Access Server was three to four
- lines behind his keyboard input. The NAS configuration was
- as follows:
-
- Access Server Acer 1100 386/20
- Modems Easy Statplex v.32 at 9600 baud
- Ram on NAS 4MB
- NAS version 1.01 with PTF 209 patches applied
- LAN Adapter NE2000
- File Server Advanced 2.15c, NE2000, 9MB RAM
-
- SOLUTION: The solution to his problem consisted of two parts. In the
- NAS software v1.01, some changes have been made to the
- DVSETUP.DV file that have resulted in a slowing of the
- screen refresh time at the remote workstation. By using the
- DVSETUP.DV from v1.0, we were able to significantly increase
- the screen response time at the remote site.
-
- Part two of the solution was to modify the customized
- software he was using. Apparently there was a lot of
- overhead in this software which, when run on a typical LAN
- workstation, did not result in noticeable degradation in
- the processing speed. However, with four users sharing the
- processor on the NAS workstation, this overhead resulted in
- a significant decrease in performance. The dealer who
- called in this problem wrote the software, so it was an easy
- matter for him to disable some of the unused functions of
- the software. The combination of these two adjustments has
- improved the performance on the NAS to the customer's
- satisfaction.
