- This article is about a subject I haven't seen much discussed in the newsgroup.
- For introduction I give the host configuration of my machine being a 486DX50 ISA
- system with 8MB Adaptec 1542B and Fujitsu 1.05GB SCSI drive. I had 386BSD up and
- running without any major problems with full sources for Unix and XFree86. Without
- the X-windows system the performance of the system is outstanding (e.g. full
- recompilation of the Kernel in less than 7mins). Since the system runs standalone for
- the time being there is no network overhead or additional deamons running. Under
- X-windows things start to behave a little differently performance-wise. I know that
- the memory requirements of all X clients are huge since they keep a copy of the
- X library in use but I would expect that and X server and two xterms will not be
- a problem. It seems that if under this 'running' configuration and a couple bash
- shells to allow for su, I do any compilation of a large program (specially if
- the program is an X-client) the system becomes unusable. What is more the X386 server
- seems to grow on size during usage, from a virtual memory size of 1.9MB to 3.5MB after
- a while (values taken for ps -aux). The swap space provided on the disk is about
- 48MB (to avoid reconfguration after memory upgrade) so the situation seems unfare.
-
- Has anybody else had any similar experiences with XFree86? Is it just a memory problem
- or is there something more to it? If it is a memory problem then the shared libraries
- will contribute towards a solution. But what are we supposed to do for the time being?
