- Well, this is just a guess, but I assume that you are not running
- *NIX on your 386. That means either DOS or Windows. You are
- probably running some kind of TCP/IP software on the PC to provide
- communications for the X server software. The TCP/IP software is
- slow because it is running on a single-tasking OS and therefore has
- to take care of a lot more than if it were running on a multi-tasking
- system. Windows is not the fastest user interface in the world, and
- if your X server is running in Windows, it is probably a little slow.
- Also, you are going through ISA, or EISA bus (I assume) for both video
- and data. ISA and EISA are a bottleneck for both communications and
- video. In short, if you want better performance, replace the whole
- machine. 8^)
-
- There are a few things that MAY help performance.
-
- 1) Get rid of windows and run the X server software under DOS.
- Make sure it supports your video card in the mode you want.
- 2) Get rid of the TCP/IP software and buy X server software
- that has the communications built in.
- 3) replace the motherboard with one that has 3 VESA local bus slots.
- Then buy a VL bus video card and a VL bus ethernet card. ( anyone
- know if VL bus ethernet cards even exist yet? ) This will get rid
- of the ISA/EISA bottleneck. You can eventually put a disk
- controller in the remaining VL bus slot.
-
- The real problem is not with the CPU (although I don't advocate the
- use of 8088 based machines).
