VERY happy with .kobo/image folder cleaning

Ok, those of you paying attention to my recent posts know that I've been working on cleaning my image folder.. Now that it's completely done and I just have to do minor maintenance when I add some new ebooks I can report on how it has changed the responsiveness of my Kobo Touch and some guesses as to why it is so much faster.

The image files I removed were tagged with the following in the filename:
- N3_FULL
- N3_LIBRARY_SHELF
- N3_SOCIAL_CURRENTREAD

I also removed and reinstalled some free ebooks I downloaded from kobo.com in the past that were after my image folder had hit its limit. I first noted the titles and erased the ebooks from my KT. Then I did a wifi sync. Added back the ebooks at kobo.com and performed another sync. After completing I cleaned the image folder to remove the newly added image files tagged with the names listed above. Did one more sync to make sure I had downloaded everything I had selected. (2 didn't sync the first time).

When my KT returned to the Home screen after the sync it responded MUCH quicker to Entering the library from the Home menu, page turns in the library, and returning to HOME from anywhere when the HW home button is pressed. Not any real systematic checking of speed but I'd say my response time for all the above has changed from 4-5 secs (or requiring a tap in a neutral location) to 2 secs or almost instant.

My guesses as to why this has worked the way it has. Not all image files are used but those that are used are IMPORTANT. The N3_FULL as far as I can see serves no purpose and is HUGE in comparison with the other image files. If an ebook has somehow defaulted to the 'generic' bookcover due to the image folder having reached it's limit, it SLOWS DOWN processing because one part of the system is sending a request for an image file and the request is timing out and you end up with a page with generic covers. If this is true it could be that there ARE NO image files associated with the ebook in question resulting in the 'timeout' delay. If the requests are all filled the KT returns quickly and the page renders with the book covers relevant to the page. Since the HOME screen, bottom carousel, Library (Books, News & Mags, Previews, Shortlist) all use cover images I believe that having no covers is a BAD THING. I cannot stress this enough for those that have large libraries installed on their KT as I have.

Hope this helps some of you out their with the response times on your KT..
