netsurf team have add the diskcache for netsurf
Actually it's a new memory cache. Although it has been designed so disk caching can be added, at the moment there isn't any.
But its a Version 2.5 and AOS 68k use 3.0 which have a diffrent plotterinterface.So there need also wait if netsurf devs add the cache to 3.0.
They do enhance 2.5 because nobody change the plotter interface currently so risc OS does not work well with 3.0.
3.0 and 2.5 are the same thing (2.5 is the release version of what is currently known as 3.0). The plotters were changed some time back (but after 2.1), and I suspect your 68k-3.0 is already using them - given it was just a simplification.
The problem with RISC OS is the new treeview code, not the plotters. However, I understand that the RISC OS version has been mostly fixed to work with this now.
maybe the new cache and less ram usage speed up netsurf more
Yes it does, certainly for NetSurf OS4. However, it has also introduced a few issues which need to be fixed before it is really usable to the same level as the old version.
