Thanks Apple, APFS is great! Especially on my SSD

Really, I love being forced to upgrade to new file systems to please your brave-new-world-esque model of delivering software! I'm also thrilled I spent so much money to get the fastest SSD possible!

Great improvements speed improvements with APFS!

I presume sarcasm?

Any details on your machine? As I don't see how a filesystem swap would lead to performance being cut in half. No file system has that much overhead.

2012 MBP, crucial SSD

After using it a bit, the performance hit isn’t quite that extreme. I am still very frustrated at being force to change file systems.

Despite benchmarks APFS has a number of terrific optimizations.

Not limited to but including copying file headers instead of the files themselves, meaning if you’re making two copies of large files they copy instantly instead of the size * time / size.

So with a 4.713 GB file copy on HFS+ it would take you 10 seconds, on APFS it would
be instantaneous. (try copying a large file twice on your desktop)

I know; apple did that in their Demo.
I'm still not thrilled at being forced to upgrade.

usually the new stuff is better than the old
APFS is a lot better. The new read only macOS system partition is solid proof of some of the massive improvements from APFS and more will come in the future.

For example, APFS allows you to share usable space among multiple partitions on a volume without pre-allocating all of the space up front...

I suspect your issue is something other than APFS.
