Half performance with the new “iCompress” :(

The biggest problem with the new version is performance. With the previous version, you could specify the number of instances (i.e. how many compressions were occuring at a time), so that you could determine the load balance yourself (ie do you want the stuff done as quickly as possible, or do you want to have some cores left free to do other work with other apps). With the new version, it determines a max number of cores you can use, not letting you use the full power of the machine. In my case, it maxes out at 50% of my cpu usage (only allowing half my cpus to be used, despite the fact that I’ve got max ram in the machine), whereas previously I could hit about 95%.
Cutting the performance of a “Pro” app in half is a major fail.

And they’ve “i”d it. They’ve dumbed down the interface and removed options to actually save batches and settings. They’re now “auto-saved”, so you’re never really sure what’s been saved & what hasn’t, and can’t save specific batches in a specific location with the files you’re compressing, and can’t just revert to a previous state by closing without saving, etc.
