I have 6,437 books in my library. With firmware 3.19.5761 I have no problems except for "My Collections" taking 2 minutes and 10 seconds to load. Whenever I have tried to upgrade the firmware past 3.19.5761 I have experienced problems. With this latest firmware update, I experience the lag I described earlier although, oddly, my collections loads in a few seconds. I was not going to update at all because of my past experiences with later firmware versions, but when I read that the collections now loaded quicker I decided to give it a try. Unfortunately, due to the overall sluggishness of everything else, I'm back with 3.19.5761. I am awaiting a faster SDcard from Amazon.com, I'll update firmware after I get it and see if it makes any difference. |

There is a performance issue that has crept into this firmware which I described earlier. I mainly see it when I open certain dialogs when reading, but it also hits when closing a book and I'd expect it will hit when going to sleep while reading (I mean the device, not me). I'm pretty sure it is related to some of the database updates being done at these times. It doesn't happen all the time, but when it does, I see about a 15 second hit. The extra books you have over me might explain the longer time it takes for you, but I'm surprised it is that much longer. And I would have expected that just after a restart it would be OK. Other than reducing the number of books on the device, there probably isn't anything you can do until the next firmware version comes out. |

I do think a faster SD card may help. Using one that's not even fast enough to stream HD video is too slow.

I wonder what the sizes are of the various tables in the database? If one never syncs wouldn't the activity table keep growing?

Wouldn't that compress database option on Kobo Utilities plug-in help?

It might help and it is worthwhile doing. But, it won't surprise me if there isn't much affect. I believe the firmware does do a compress, I'm just not sure when. If it was me, I'd be doing it during the startup.

For the Event table, it can be cleaned up. If you don't care about the stats, you can just delete all the rows. Some rows can be removed safely without affecting the stats, but I'd need to check my notes before suggesting which. Reducing the total number of rows should help performance, but I have never checked. There were some problems with specific event types in the past, but I think those have been fixed. But, as you are mentioning syncs, you might have meant the AnalyticEvents table. I would expect that to get flushed with each sync. Clearing that might help. And there is a function in my Kobo Utilities plugin to add a trigger to prevent anything from being added to this table. But, I don't believe this table is the reason for the performance issues I have been seeing. |

Thanks--I can handle a one-off nag. It would only be annoying if I was repeatedly nagged to sync!
