STILL having this issue on the latest version of MM - 4.1.25.1889. IPhone 7, 128GB.
Has been like this for years, I don't know of anything else that 'non-destructively' copies music to an IPhone, and I'm reluctantly having to use ITunes.

Nearly 40 minutes to copy 54 tracks, it's been stuck on song 40-of for about ten minutes now. Welcome back to 1996 everyone!

this issue still here, so I imagine that people sent bug reports and developers didn't found solution?

Take more than one hour to copy 250 songs

iOS 7.1.2 (iPhone 4, so I can not upgrade anymore)
MediaMonkey 4.1.9.1764

I have found that once I restored my Ipod Touch 3G to the the factory default and removed Cydia, ie. no longer Jailbroken, the sync process seems to be much faster.

As suggested before, send a debug log (step 4b) capturing the sync to support: http://www.mediamonkey.com/forum/viewto ... ?f=12&t=69

4.1.1.1703 syncing 2048 tracks to iPhone 4 with 7.1 for close to 20 hrs and it's at the track 1355. It never used to be a problem. It starts syncing fast ~5-10 secs per track, and then suddenly performance drops slower and slower. Now syncing for one ~4 minute long track takes about 1 minute ++.

Just noticed if you start with an empty library on your iOS device syncing works fine, but when you do an auto-sync the second time it hangs/gets VERY slow around the 40th song.

For people having issues try deleting everything in your iTunes_Control folder using iFunbox or something similar. Reboot your phone and make sure the Music app has no content. Resync and see if it works for you.

I've tried this method on an iPhone 5C jailbroken with 7.0.4 and an iPhone 5S with 7.1.1. Both devices would hang/get VERY slow on the second sync after ~35-40 songs but work fine when starting "fresh". If you only add one or two albums per sync after the first sync it works fine as well (less than 35-40 songs).

Using 4.1.2 beta on Windows 7x64

Sync is still extremely slow with my ipod. Takes minutes to figure out what is on the device, then achingly slow to sync tracks.

So after much experimenting I am no longer able to reproduce the issue. It seemed to be a problem with iOS version 7.0, because once I updated it to 7.1.1 on my iPhone 4, the sync speed went right back to normal. (the iPhones performance is also much better in general).

I have the same problem syncronizing with iphone 4. This is a persistant problem that also occured in previous versions. What is the point of a music management system as sophisticated as MediaMonkey if you can't syncronize quickly with your device? I hate to say it but, I think that I'm going to have to return itunes.?¡?$%&!!!

I only sync about 2500 files to my iPhone but I also experience slow sync times since MM 4.1. I am working on providing logs to the devs.

I will do the log soon, been travelling and not at my home computer for a while.

From what I have been reading this problem seems to occur across all devices when syncing a large number of songs.
When I sync smaller sets <5000 Songs I dont seem to have a problem, but the large set > 10000 Songs seem to cause the excruciatingly slow sync times.

Would love to hear if someone has had success with large library syncs?

Maybe that will give the Devs something to look at ??

The same still stands:

That is exactly the same thing that is happening on mine.

I am also having very slow scan/sync issues with my ipod classic. It takes seemingly forever to scan the hard drive (used to take a couple of minutes in mm v3 even with 20,000 + tracks). I have just installed MM4 - resisted the upgrade - this is the most annoying part. Can you undo whatever you "upgraded" re big ipods?
