- The disk was 200 MB. And available memory for cache buffering
- was 9 MB. It should be enough. Using PC:s to transfer 10 MB the write times
- are around 60 seconds to the same disk.

- 100-user version. Memory was configured as installation does it.

-
- PSERVER, AFP and ATPS were running, with two PRINTER queues and one ATPS queue.
- There were no other tasks during the test.
- The server utilisation was 0% before the test begun and it jumped to around
- 20% during the transfer.

- Why does a 486/33 PC with 8 MB of RAM tansfer 10 MB in less than 60 seconds?

-
- Some how transfer times from Mac to NW4Mac are slow when very larger files
- are used (over 10 MB). This makes Netware servers useless in an environment
- where imagedata have to be transfer to the server. Reading isn't a problem.
- Only 2 minutes for the 26 MB file.
-
- I am not counting out a configuration problem.
