Kindle super slow with Send to Kindle — anyone else?
A few days ago I downloaded a study Bible with a ton of notes — the Straubinger Bible (1948) — to put on my Kindle. The file was a 4.6 MB EPUB.We all know Kindle doesn’t support EPUB natively. If you use Send to Kindle, email, or the app, Amazon’s servers convert it to a compatible format.
So I sent the book via Send to Kindle. When I opened it, it was painfully slow. At first I thought it was normal because the Kindle had to process all those notes, but I wasn’t convinced. Recently I tried Calibre to sideload files and transferred the same Straubinger Bible again. The difference was insane: opens instantly, page turns are snappy, it just flies.
I tested this again with other 300-page books with almost no notes. Same result. Send to Kindle = laggy. Calibre = super fast.
Anyone else noticed this? Is Amazon bloating the files during conversion or what?
