simple html pages slow to render

[John Rickman Iyonix]

The Gaydon online parish magazine is a single HTML file which 
references a common CSS file.

http://www.gaydon.org.uk/mags.html

It takes on average 31 seconds to load and display a magazine using 
NetSurf #3055 on an Iyonix. Javascript on or off makes no difference.

Using NetSurf 3.2 the page load is instantaneous.

Not sure if this counts as a bug but I have submitted a report to the 
tracker.

The 31secs bit on #3055 occurs on downloading a magazine, not on downloading
the page above. I can confirm this on my Iyonix running OS5.22 and a
Raspberry Pi running OS 5.23 (03Nov15). It's all good on NetSurf 2.9 on Mac
VRPC at 0.2s.

Apologies, it was not clear from my post that the problem was with 
links to magazines on the quoted URL and not with the URL itself

http://www.gaydon.org.uk/mags.html points to a list of magazines. This page 
loads quickly but links out of this page to a monthly magazine take a long time.
eg http://www.gaydon.org.uk/mags/mag1511.html

0.2 seconds for the page quoted, and 0.3 seconds for the magazine pages,
with #3055 on an ARMX6

A missing file shouldn't cause a timeout though - just a response from
the server containing error 404.

30s is an interesting duration NetSurf-wise, that is how long before 
fetches time-out. From a look at the log :-

OK, I'd missed that the page mentioned wasn't the one with the
problem.  They all load in 2s or less here, so it might be a RISC OS
specific issue.

Tested this on Netsurf #2817 with the same result - the issue has clearly
been around for a bit.

 Loading in 0.8 seconds here.  Can you attach a log to the bug report,
 otherwise it's unlikely the problem will be identified?

Not an answer to the question as asked, but with #3048 the page loads 
in 0.2 seconds.

Assumptions!!!

We RISC OS users think that NetSurf is a RISC OS browser when in fact 
it is multi-platform. Indeed it can even run on an Amiga.

A fresh built nsgtk on Ubuntu loads the magazines in 0.1s.

The problem was introduced between 28/11/2014 and 6/01/2015.
(#2398) is fast, (#2509) is slow.

If you have any builds between these two it would help to pin it down 
to just a few potential culprit changes.

Thanks for spotting the error in my html Chris, however, As David has 
mentioned in a subsequent post, it is not the whole story.
I have removed the redundant reference and uploaded the page, but it 
still takes 31 seconds to render.
 http://www.gaydon.org.uk/mags/mag1511.html


BTW the page loads instantly in the off line version of the web pages.

404 is page not found. Other missing files like css should be ignored 
by the browser. In any case if the file didn't exist the server would 
respond with an error straight away.

I've been exclusively using the Atari CI builds for a long time
and it has become my prime browser on the Atari because it makes
the best job or rendering most pages.

I usually update 2-3 times each month. I can't remember when
the last one was unstable.

There are some issues, speed being the main one. This isn't
a JS issue because there isn't a JS build for the Atari.
It would be nice to try one.

Great work and a big thanks to everyone involved.

I think the progress page needs an update :-)

It's file not found.  Any missing file on a web server will result in
a 404, but if it's a linked file like CSS you won't see the error
(it'll just be treated as a missing file, as you say).

In any case, it looks like that's not the reason for the timeout.

I find that magazines take around 32s to display on my RiscPC using 
CI#3048. However if I do a full save they render from hard disc much 
more rapidly.

I noticed that doing a full save did not save the CSS file so running 
the application still downloaded it from the server. I saved the CSS 
file locally and updated the link, whoch didn't make a lot of 
difference.

Has 'full save' changed? It always used to save CSS files. This could 
be a serious problem because the page wouldn't render properly if the 
original file was no longer available.
