- To users of the Netmanage Chameleon package.
-
- I wonder if you have come across any performance problems. We have.
-
- On a basically VERY underused network segment, we see around a 100 kb/s
- throughput using a variety of DOS-based FTP's (NCSA, Excelan), both incoming
- and outgoing with respect to the DOS machine. This is about the same as
- some 386 and 486 SCO System V (unix) machines we have on this segment.
- Out of Chameleon, however, this drops to between 8-20 kb/s, but only on the
- outgoing side relative to the PC running Windows. Incoming speeds are
- comparable to the DOS-based or unix speeds.
-
- We have been in touch with Netmanage on this and have even been called
- a beta-site. They tell us that the TCP/IP buffers have been set up at
- 4KB incoming and 1KB outgoing and that this is not adjustable! Of course,
- it would be wonderful if this were allowed in a future release, but that
- doesn't move a series of 10MB *.tif files off my pc any faster today. We can,
- and will, drop back to DOS for large data transfers like this, but it would be
- nice to work on other things while that is going on. In other words, I'd like
- to stay in Windows all day if I could.
-
- Is there anything in Windows that we can do to improve performance, i.e.
- increase a priority or permanently allocate RAM to an application? Our
- knowledge in this area is lacking. Any ideas?
