Seriously though, the devices have enough memory to keep the applications and several (large) documents open. Increasing cache would only be noticeable when you would browse pages (back and forth) a lot, which is not a typical use case.
As yacoob says, flash is not known of its quick throughput and it has endurance limits which makes it not particularly suitable for use as cache. |
mmm..
I think that the thing need to be tested..
most likely the advantage can be just in page rendering time..
and that would be a very good thing..
as you and all users have for sure noticed when you open a large pdf document the next 2-3 pages after the one you are reading get shown immediately if you go on quickly..
the forth one requires the pause with the popup messagebox ..
so this means that the first ones have been already rendered and are ready to show in cache.. the other ones need still to be read and rendered..
so think if we have a cache where all the page of the book are already rendered.. even if this cache is not on the physical memory..
most likely the bottle neck is not on the disk access time but on the cpu computational time.. pdf is not simple to render and the cpu of the reader is not a quadcore for sure..
so while you read your page the reader could have the time to pre-render all the rest of the book..
so the thing have to be tested..
so some more questions..
1-do you think that the access time would be faster on the rom or on the sd card ? on the rom there is 58 mb of free space.. while on the sd there is a lot of space.. obviously that test should be done with a large swap on the sd card, but I'm curious the same about this..
2-how much physical memory has the device ?
3-if a swap is enabled, the cache in uds would be enlarged automatically or some tweak need to be done somewhere ? and where ?
@yacoob
well you are right too
