Nelson,
We are working on a CORBA-based java client that is pretty weighty in
terms of Swing components -- JSplitPane, bunches of JInternalFrames,
etc., all on the screen at once. Working on Linux using JDK117 v3, no
JIT, it is certainly bearable, IMO. It is slow, Java in general is slow,
unfortunately. But I've tried some alternatives, and have come away
feeling that this is the better. Some of my (possibly subjective)
observations:
(1) native threads are broken in JDK 117 v3. It's been talked about on
the list, but never addressed. Components will not draw properly, frames
will occassionally come up gray boxes, menus won't show, etc.
(2) JDK 1.2 pre2 fonts are still ugly. There was some sizing problem
with v1 that is fixed, but the font.properties file does no justice to
running java on linux. I will try to muck around and come up with
something decent, if I do I'll post it. As it stands, it's an eyesore.
Demos to clients would simply be embarassing.
(3) I tried a current project with JDK1.2 on NT, and found it ran
slower! Weird. I need to look into it, because it's hard to believe
(Symantec jit should be rather good), but it brought the machine to
paging hell.
So on my little 233 i586, the 117v3 with green threads is the most
bearable and pleasant Swing environment I have found. As for JITs on
linux, I have never seen TYA improve GUI performance to the extent that
I notice it qualitatively. Since I have enough variables to deal with, I
run without it.
Good luck,
-Armen
