Why is xfractint so darn slow? Heck, DOS Fractint under DOSEMU is faster!

Yeah, it takes almost 8  seconds to render a mandlebrot here.

What version are you guys using?  Version 3.0?  Or an older version?

No doubt the biggest factor in reducing the speed is the absence of the hand
coded assembler routines that make the DOS Fractint so fast.

Hmmm.  I suppose that since Linux runs on Intel machines, it would be possible
to make a special Linux version of xfractint that would make use of the
80x86 assembler.  MUCH of the asm code would have to be rewritten for
32 bit addressing as all of it is currently written for 16 bit real mode.
Still, it would be possible...

: Very unloaded system:  AMD486DX100, 20MB, XFree863.1.2, S3 video,
: 1.3.28 kernel, Xfractint 2.03...  Takes about 8 seconds for all three
: passes to render a mandelbrot.

On my very similar system (AMD486/100, 16MB, XFree86 3.1.2, S3 video,
NCR SCSI-controller, 1.2.13 kernel & Xfractint 2.03) it takes only four
seconds to render the default mandelbrot. Of course, if I zoom to a place
which needs lots of iterations (=a lot of black), the time goes up.

1. Tin newsreader, slow slow slow

err, this may, or may not be off topic.  i am using:

tin pre-1.4 release 19990927 ("Nine While Nine")
[UNIX] (c) Copyright 1991-99 Eain Lea.

usenet.xxx.edu InterNetNews NNRP server INN 1.7.2 08-Dec-1997
ready (posting ok).

and, yes, i do attend "xxx" univeristy. i never miss a class!

i'm just a lowly user :)  anyhow, when it reads a newsgroup, it has a
status type thing where it says 145674/4564324 like that.  it seems to
get a _huge_ portion right off the bat, then it slows to increments of
fifty.  i _could_ install tin on my linux laptop, but space is ver
limited.  and, what would be the point? i still need a connection to the
net. as a user, i use the version on my schools sun computers.  can
i get tin to work faster at bringing up a newsgroup?

otherwise, tin is neato :)
