There was much discussion about a year ago about the cache performance on
RISC OS, and there were some code changes, but I would like to add the
results of some investigations of the Netsurf v3.4 cache on my Iyonix,
running RISC OS 5.23 (11 Oct 2015).
In the past I had problems with the cache taking large amounts of disc
space, and the resulting long backup times for !Boot, so my current
settings are 10MB space, expiring after 2 days.
However, the actual space usage was 45MB (as measured by Filer Count),
and it contained 210 files. What was more difficult to find was that
there were 7,298 directories with 8 levels, which occupied another 14MB,
of which 6,412 contained no files at any lower level. So only 886
directories actually contained the 210 files of cached data. Enumeration
of the cache took about 2 minutes.
I decided to delete all 6,412 directories that contained no data, saving
about 12MB of disc space. More importantly, counting or enumerating all
the cache now takes about 7 seconds. There are still the same number of
files and cached bytes.
Netsurf itself still seems to work, but I have not noticed any change in
So, some questions:
- When are cached files deleted to meet the configured size & expiry?
- Are directories included in the space used?
- Are directories ever deleted? If so, when?
- Will deletion of empty directories cause any problems for Netsurf?
I have looked at the help ... but that says that files are not deleted by
Netsurf, and makes no mention of directories. It also refers to a
'Perform maintenance' button which can be used to delete redundant files
... but this is nowhere to be seen!

Please reply to the list, not directly to me.
If you visit about:config does it show the correct values for these
options? Did you set them whilst NetSurf was running? (it won't pick
them up until the next launch, and may overwrite the file in the
I have this annoying issue with the current Netsurf for the Amiga 68k
in that lots of websites returns with this annoying error "Unable to
fetch document." My understanding this is the cause because of
timeout. Is there anyone this can be fixed. Also another issue when
viewing pages, it open them in tile 100 by 100 and this is annoying
and unpleasurable is there anyone this can be fixed?
Other questions to ask. Will there be in the future support for html5
that will allow gmail to be opened in full html5 mode and not in
classical mode? Will we be able to run html5 games or view html5
movies just fine? My understanding is that the hardware spec is too
inferior for this. Can you make two versions...one that works fine on
classic Amiga (with Vampire installed) and others on WinUAE where
hardware power is no longer a factor?
The one for WinUAE will have full functioning power both RAM, speed
and EVEN RTG to be able to run the latest FireFox...so it should be
able to run the heavy require minimum 500 MB of RAM NetSurf that
supports lots of the bells and whistles.
I know the common sense logical question...why? What is the purpose?
What is the point? I will answer it by this....instead of waiting for
a hardware to become strong enough to port this...we have the software
already build and ready for the 68k Amiga that...all it takes is
having a more powerful hardware. This way, the hurdle of having a
software or someone programming is...is all over...because the
software is simply waiting for the hardware to catch up which is
easier than the otherway around.
Please can someone consider?

I've just reported to the bug tracker that NetSurf is now refusing to
load and exiting with a Segmentation fault. I have been running CI #
3625 since 9 Aug without any problems before this morning. Reverting
to #3594 gives the same error.
Should I delete the files in !Boot.Choices.WWW.NetSurf ? That strikes
me as a possible place for a problem to be located that clearly isn't
in the actual application.
When trying to shut down, NS seemed to just loop. I was unable to find any
way of gaining access to the Iyo 100 so switched of power. On re starting
and trying to run NS it seems to loop. Cntr break restarts the machine and
everything else appears to run. I had been accessing a large number of
sites both with that last session and with previous sessions over the last
How should I proceed?
Further to my posting just now, Organizer has been affected or is also
involved. When I try to load it the error message "file does not start
with orgdata" appears. It has been overwritten by NS.
I'm using Virtual RiscPC on my ol' Windows XP laptop while away from
base. Various wrinkles of this setup are still unfamiliar to me.
One is that Netsurf (recent, #3538) too quickly eats up all the free
What can I do to avoid this? I guess I either need to fix Netsurf or
need to find a way to make Windows give more memory to VRPC. Haven't
yet found a way to do either; advice welcome, please.
