Is it possible to run the same benchmark on the Ben NanoNote? 1.5 G should fit on the memory card and as far as I understood you the ZIM software has been already ported to the NN?
Yes, this would be really interesting. The same test, with the ZIM on a DVD would also be interesting.
Because I wonder how the caches impact the result on the NN and what the optimal settings would be. As far as you say that the caches don't have a real impact on "big" hardware, we could just go with the optimal settings for the NN as defaults in the zimlib.
Yes.
I have also multiply by 1000 the dirent cache without seing any sensitive improvement. But here again, the test should be done with a DVD player to help to determine the best default value.
In any case, the results are really encouraging, although that's a deception for me that we can not save more disk usage with LZMA. Should be interesting to make the same benchmarks with a 2MB big cluster.

If you read my original mail thoroughly again, you will notice, that the testing was done with the zim on a DVD.
I will do the testing on the NanoNote in the next days and will inform you of course.
My impression is, that lzma will get better compression with 2MB clusters. But the gain will be quite small. Maybe we save another 1%. The cost is, that the memory consumption will be greatly increased and performance decreased. We should really keep the 1MB cluster size.
