Matt:
The transfer speed is a floating average of the actual megabytes (MB) per second for the physical file transfer.

If the OS is caching or the file is not really transferring (but saying it is), it's possible you might see higher numbers than you expect.

Whichever way you look at it, there's something bad happening. The process has been running for several days now and I've never seen a reported speed of less than 30 MB/sec (50 MB/sec is typical). The source files are on another PC and the link has an absolute maximum capacity of 12.5 MB/sec. MC has converted 66% of 287 GB in about 80 hours and my arithmetic makes that 0.65 MB/sec. If I add the size of the output files the figure creeps up to 0.78 MB/sec.

It's hard to avoid the conclusion that MC with its 50 MB/sec is providing a seriously optimistic figure, either miscalculating or counting the same data many times.

Of course I might have made a mistake but you're welcome to check my calculations. And it goes without saying that the speed is what it is, and lowering the figure that MC reports isn't going to make things happen any quicker!

Just a quick note to say that everything now seems to be working OK. Thanks for all the help.

Problems, there have been a few:


* When syncing using the LAME encoder, MC12 sometimes reports "Error", sometimes hangs, for no apparent reason (about 0.1% of conversions). Resyncing always fixes the problem.
* The artist list in my iPod is sorted weirdly. iTunes sorts A-Z, 0-9. MC12 sorts 9-0, A-Z. Bizarre.
* I haven't been able to make any sense of the "Delete from handheld any files not in sync list" and "Resync if date modified has changed" options. I know what I think they ought to do but in practice they never seem to do what I'm expecting. When I get time I'll create a small test library to see if I can make sense of them.
