Early versions of the atari port crashed because of stack size issues
(caused within mintlib regex module, called by NetSurf CSS parser, while
it was processing exorbitant strings (3k, which expanded to several
MegaBytes within mintlib regex module)...).

I prevented the crash by compiling mintlib with the
+DEFS=-DREGEX_MALLOC 
define. 

This is also applied to the CI builds. 

Just a guess: there is some kind of slowdown when doing excessive malloc
operations with MiNT.

Worth a try but it still took a little over 18 minutes.
I reckon about the same time as it was before.

Interesting figures.
On my ARMiniX with Dev Cl #3244 and Javascript enabled, it takes a bit less
than 4 seconds, everytime.

I can confirm with an older build that this page takes an insanely long time 
to load with the Atari build. Since this seems to be specific to the Atari 
port I suppose only an Atari developer could figure out what is going on.

I have an Atari 2.9 version lying around and with that build it takes 100 secs 
to render that page. Still very slow but much less so than with the 3.* 
builds.

There is a lot of CSS on those git pages, I believe some CSS caching
is being looked into to reduce the amount of processing required.

In my dabblings with building a 68k version of NetSurf for AmigaOS 3,
I've noticed that the text layout and rendering code plays a big part
in the speed NetSurf loads pages.  On AmigaOS 3, rendering outline
font glyphs is painfully slow, and I think this is down to the 68k.

I notice the Atari code has three font rendering engines; VDI,
FreeType and Internal.  It look like FreeType and Internal are
enabled, and FreeType is the default.

Try setting the following in your Choices file:
atari_font_driver:internal

See if that makes any perceivable difference.

FWIW on this virtual RPC with JavaScript and css running the
download/render process takes c10.5 seconds.

I just tried it with CI#3254 on an Iyonix.  Took about 24 sec.

If you're not on a very recent CI build, I would recommend you get
one.  Very slow rendering was fixed a couple of months ago.

About 43s here on RPC with standard ADSL connection. CI#3250. Firefox 
on the macbook pro takes 2s over the same connection.

I am using a build from today and I know it is never going to be
lighting quick on an M68060 but my point is that the speed seems
unduly slow over an adsl link that normally downloads at 350k/s.

I have reported before that Netsurf on the Atari seems slow at
downloading pages so it might just be an issue with how Netsurf is
using the OS ?  It's not my area of expertise.

Is it because there are a lot of files ?
Is it a cache issue ?

Long delays can often be observed on other pages. The git url is
a useful test case because it is fairly stable and repeatable.

No criticism, I am hoping this might help the devs find some speed
improvements.

Regards,

Peter

Takes 34.9 seconds on this SA RPC using Netsurf 3.3.  Tried it on Windows
box on Firefox and it loaded in less than a couple of seconds.  Display on
both Firefox and Netsurf seemed essentially the same - just a heading and
then a page of 1430 numbered lines of code.  Is that what it is supposed to
look like?  Doesn't seem to be much rendering going on!

About 4 seconds here, ARMX6 and NS 3254

But our internet is very variable: when lots of households are on line, it
can be slow!
