The performance on a single file is the same as HFS Extended. So for the really speed critical tasks, like editing uncompressed video, APFS should be just as suitable as HFS Extended. In our testing, it appears to be much harder to get a corrupted volume with APFS than with HFS Extended. APFS has native 'hardlinks', HFS+ has to fake them in hidden file. This hidden file can get huge. In a TimeMachine backup, it will grow huge and gradually makes TimeMachine slow, and, very difficult (slow) to copy the TM backup to another drive. APFS most probably helps TimeMachine to be quicker. APFS verifies the integrity of the metadata.

Convert APFS volumes to HFS+ volumes. Create a recovery media in case of system disk conversion. Wizard helps to select the desired volume for conversion, gives you the option to back it up, then quickly performs the conversion.

blogbench
Iconkit 4 0 1 – icon resizer for app development. Blogbench is a filesystem stress tool that imitates a hosting environment. While it sounds like it may not be an ideal benchmarking utility for a laptop or workstation, Blogbench creates multiple write / read / rewrite operations, uses 8K chunks of data and was used primarily because of multi-threading.

Nx power lite. And now the fun part – Blogbench creates timely statistics, which helps to visualise the transfer over time:

APFS vs HFS+?
There isn't really a ‘versus' here – it's hard to fully compare two filesystems that were created 2 decades apart. While modern filesystems may have some disadvantages, they offer a whole bunch of new features and improvements that a normal user is even unaware of.
Older filesystems are fast – all of the widely used ones can saturate SATA hardware with no issues. But compared to modern ones, they offer next to no traits other than 'you can store objects here'. Over time, additional layers of software improvements were added to some filesystems, but also new ones were created from scratch, with a variety of new and old, but now built-in capabilities. And while one can think that the later should be faster – it sometimes isn't because of how things work. In short: faster doesn't necessarily mean better and all of the above charts only show how fast (or slow) things are. If I were to compare NTFS to ReFS or EXT4 to ZFS, some new bottlenecks would also arise in specific workflows and specific hardware configurations.
Apple didn't officially said much about APFS and most websites are just quoting Apple's developer documentation: 'Apple File System (…) features strong encryption, copy-on-write metadata, space sharing, cloning for files and directories, snapshots, fast directory sizing, atomic safe-save primitives, and improved file system fundamentals'.
I could speculate on why some tests shown a decreased performance but my knowledge on the subject is thin and that would just be some maybes and probablys (for example: I have no idea why encrypted HFS+ achieved better results than plain HFS+ in some tests but I repeated these tests with a comparable outcome) so instead, here are some observations:
- in some cases APFS appears to be slightly slower than HFS+ when it comes to writing data, especially in smaller chunks
- APFS appears to be a lot faster than HFS+ when it comes to reading data
- AFPS' built-in encryption shows decreased throughput speeds in comparison to HFS+ with FileVault2
- seek rates seem a tiny bit higher with APFS but that would be unnoticable on most workflows
- apart from speeds, APFS introduces a lot of under-the-hood improvements
And again, all these benchmarks were performed on a really fast NVMe SSD disk and even on this disk, the differences aren't big. On SATA SSD there should't be any visible problems with the filesystem upgrade.
