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!
Does Netsurf not save its hotlist and history till the user quits the
Last night I was looking for tips on how to use CSS for something on
my website, came across a wonderful site and immediately added it to
my Netsurf hotlist. An hour later, some other application froze and
the computer had to be rebooted.
Today I wanted to return to that site about CSS, but there was no
record of it in my hotlist. Nor in my history. Tried all sorts of
searches via Google and Duckduck -- no luck. Bereft.
Is there any way to make Netsurf save history and hotlist during a
session? Or am I misunderstanding something?
As for the site I lost, maybe somebody else knows it and could point
me in the right direction.
- Exceptionally clean design. The bits of code within sentences were
presented with a grey background.
- Fine use of language, not cutesy or nerdy or commercial.
- It had a surprisingly nifty name, one syllable I think, almost in
the league of web.com or code.com -- so simple it made me wonder that
the writers found it still available.
- Further surprise when I got to a deeper page: it was a UK company,
despite the ".com" domain, located somewhere like Shoreditch or

netsurf site using the "users list" unsubscribe feature. It just says no

A little problem with the <hr> tag in Netsurf 3.5 and 3.6.
I have a simple html doc. in which horizontal rules are used:
<hr align="center" width="50%"><br />
This displays as expected in Netsurf 3.0 and Firefox but in Netsurf 3.5
and 3.6 it produces a full width rule.
Is it me or Netsurf that has missed something?
Best regards, Philip.
After a bit of fiddling I got the default window position to where I
want it - full width, just below the menu bar at the top and just
above the icon bar at the bottom. I've ticked 'Stagger window
This is fine when you first run NetSurf but I would expect NetSurf to
use the default position whenever the first window is opened
regardless of what went before (i.e. no other windows are open).
It doesn't work like that. You can open a window in the default
position, close it and open another window. This gets staggered up or
down even if there's no window to stagger it from.
I feel a bug report coming on, although it's really only a design
oversight. In the mean time I might be better off with 'stagger
