Further to my previous efforts I have made an attempt to improve the disc cache performance even more. I would again be grateful if suitably interested users could try test CI build 2771 or later.
The previous changes switched to using a small number of large files to hold all the "small" entries within the cache instead of them using individual files. This drastically improved the cache performance on several RISC OS machines. The new update extended this approach so that these block files get created with their maximum size instead of being grown every time a new cache entry is added. This change should be beneficial to RISC OS users as filecore is (apparently) dreadful at this kind of usage pattern. I have also adjusted how the computation of low bandwidth is made to try and make it more stable and less "trigger happy". I would be interested in getting the details from using the updated test release in the same way as previously detailed. (The overall bandwidth message from the log) I am especially interested in testing from the Iyonix as this was right on the edge of usefulness previously. It is probably not worth bothering with the RPi and ARM mini platforms as their reported bandwidth last time was awful and I do not envisage an improvement of that many orders of magnitude. -- Regards Vincent http://www.kyllikki.org/
