You said the 32-bit 3.7 version is a lot faster than the 64-bit 3.7 on the same computer? What about version 1.48 on that computer... is it even faster?

I'm finding this a bit strange, as I've never noticed a difference between calibre 32-bit and 64-bit, except for the fact that calibre 64-bit is capable of converting some huge books which the 32-bit version can't handle due to lack of memory. Also, because it can use a lot more memory, the 64-bit version can convert more books at the same time, if you have the CPU-resources (cores) available.

This is a completely expected difference however, and the most important (maybe even only) reason for running the 64-bit version.
I need to do some testing to see if 1.48 is any faster. Again...it could be perception more than reality, but as I use calibre 64bit - it just doesn't seem quite right. I think I need more time in there to convince myself. Thanks
