Glo Speedy Glo please......

jackastor · 03-08-2013, 04:20 PM

IS there any way that the Kobo Glo can be sped up or streamlined especially with the use of book shelves? Is there some secret setting, configuration that we all need to do to make this happen? Does anyone have any tips on how to speed up the Glo? Or some magic incantation to make it seem super fast? Anyone? Or is it just some bad coding in the firmware that makes things like Shelve management horrendous?

Regards

One of these will make your Glo go real fast...

I don't know about shelves, I only have 400 books on my Glo and haven't felt the need to create any shelves yet, but might when I get more books. From what davidfor has said on the subject it seems that less-than-optimal code/design is at least part of the problem.

But more generally the speed of things like displaying covers and opening books seems to depend a lot on whether the cover, book, etc. is already in memory. The first time I open a book it might take 3 seconds, but thereafter it only takes half a second, unless I power off the Glo or do something else that pushes the book out of memory in the meantime.

So I think anything that reduces the size of the objects the Glo has to manipulate will help. E.g. a smaller cover image will take up less memory and so be more likely to still be in memory the next time it is needed and less likely to push something else out of memory.

I noticed that kepubs downloaded from Kobo have black and white cover images, but when the Glo creates the cover image from the first page of a sideloaded book it stores it as a colour image, which takes more space. However if you send the cover image seperately using Calibre you can set it to send black and white images for sideloaded books too.

Another thing is that cover images are not saved for later use if the book is on the external micro SD card, and so will be much slower to display if they are not in memory. I imagine generating the cover will use more memory than loading a pre-generated one too, and so push more things out of memory and thus slow down other operations. You could get around this by replacing the internal card with a larger one and keep as many books as possible on the internal card rather than the external card.

Some books just seem to be badly organised. I have some where the cover and table of contents are at the end of the book that take a long time to open even in Calibre's book viewer, I think it would be possible to speed them up by reorganising the book but I haven't looked into this yet. But there does seem to be a connection between books that are badly formatted or structured and books that are slow to load or have other problems.

Overall I am very happy with the speed of my Glo, but any ideas to make it even faster are welcome, especially as more books are added (I hope to have a few thousand books one day :-)

How do you do this? I googled but couldn't find a how-to.

Customise the KoboTouch plugin in Calibre (Preferences --> Plugins --> Device interface plugins --> KoboTouch) and tick the "Upload covers for books" and "Upload Black and White Covers" boxes.

Note that the sent covers will be stretched to 3:4 ratio unless you also tick "Keep cover aspect ratio". Kepubs from Kobo seem to keep the original aspect ratio.

Well if you want to speed up the shelves and cover loading a new internal SD helps a lot, as long as you get one with very good random read/write speed, have a look here I list the card i put in and what is happening faster with the new one compared to the old one.

Shhh, nobody tell him about the secret code that Kobo built in that makes everything go super fast. We don't want it to get out or everyone will be 100% happy with their Kobo e-readers, and of course Kobo don't want that!

Personally I like the sling shot method offered up earlier... easier then remember how to punch in the code to get the power up.

moffattm · 03-10-2013, 06:09 PM

Or maybe add some "go faster racing stripes" to your Glo?

davidfor · 03-10-2013, 08:51 PM

Do they have a red Glo? Red things are always faster.

Not so sure about this. They were advertising the new Lotus Exigo in the lifts at the office today. It was yellow. And fast.
