At any rate, the fact that hfs+ gives much faster boot times makes it clear APFS aint quite ready for prime time
I can’t even install 10.13.4. No matter terminal, AppStore update, or full OS installer. All pretend started the update (e.g. with the Apple logo, loading bar, and time remaining), but finish in just 2-3min, restart, then stay at 10.13.3. Nothing changed. May be I should enable SIP and try again.

Sorry for the new post... anyway yes... problem solved!
I've been using trim off. Today I tried turn trim on and it was terrible. boot is too much slow. I again turned it off. Apple doesn't care about this issue.
And here I thought the time had finally come for me to resintall High Sierra...
...thanks for the headsup!
I will check later boot time with my 2010 mid MacBook Pro, HFS+ RAID-0 SSD 850 Evo, 16gb ram, just updated last night with High Sierra 10.13.4.
update: boot time starting from power button to desktop = 33.5 secs.

Chiming in with my experience here.
MBP Retina 15" Early 2013, stock SSD
MacOS 10.13.4
Filevault DISABLED
I started experiencing long boot times as soon as I updated from macOS 10.12 to 10.13 back in November. My previous startups had been taking 10-15 seconds, and since the update I'd been clocking them at 1 min to 1 min 30 seconds. No updates had fixed it. Today I had the day off and couldn't take it any more.
Verbose mode didn't show me much that I understood besides some errors that have been previously screenshot in this thread.
I started my troubleshoot by clocking a normal startup at 1 min 25 seconds from POST chime to getting to the user login window.
I'd already tried:
I'll report back if slow boots recur. Keep your fingers crossed.

I'd already tried:
- Disk Repair in recovery
- NVRAM, SMC reset
- Onyx
- Removing all startup items, launch agents and daemons
- Booted to recovery, erased and reformatted my drive as MacOS Extended (Journaled)
- Reinstalled macOS high sierra from recovery (this automatically converts the MacOS Extended volume to APFS, which probably rendered step 1 pointless)
- When this was done, I set up a dummy user as new (no time machine), skipped logging in with iCloud, no file vault, and got to the desktop.
- Shut down unit, turned it back on. 15 seconds from POST chime to login window! So a clean install fixed it, I wonder if my time machine backup will bring it back.
- Repeated steps 1 and 2, this time restoring from my latest time machine backup. Got to my desktop, shut down and powered back up. Still boots in 15 seconds.
I'll report back if slow boots recur. Keep your fingers crossed.

July 2018, 10.13.5 is out, a two days old iMac (2017 base, Fusion Drive 1TB, RAM expanded to 24 GB) takes 47 seconds from button press to login screen. When I installed the OS on an external SSD (400/400 MB/s speeds), the time remained precisely the same, 47 seconds. My Hackintosh (i7-4770s, EVO 850, 16 GB RAM) needs about 8-9 seconds. My rMB 2016, m5/512, takes 21 seconds.
I wonder whether I can get that iMac to run Sierra?

Do have a utility such as little snitch which will tell you if during boot attempts were made to connect to the internet? I've have had to approve a whole bunch of connections during boot in little snitch, some from my own apps, others from apple apps. Unclear whether the apple apps are being driven by other apps or by some apple function.
My boots take on the order of a couple of minutes due to all the internet connections being made by programs I have installed.

Nope. I looked at logs, but the only weird thing I see is launchd[1] taking a break of 10 seconds to respawn every boot. I'm now curious whether it would work faster with wifi off...
I've flipped-flopped about 40 times now throughout my testing and playing around. Here's my subjective observations on MY system.
After an initial upgrade from an HFS+ installed macOS, sometimes the conversion process leaves the drive in disarray somehow. If you stay with APFS long enough, for me it seems to work itself out, but it can take a very long time, and sometimes not at all.
I think there is a lot of reindexing, re-trimming, and re-organizing directories going on in the background.
I've found that if you (as mentioned by another member) move your install to a back-up drive by way of cloning, and format the main drive fresh (APFS is fine), then move your install back to that drive, it will clear up most if not all of your complaints. I think the conversion process takes a left-turn sometimes.
Also, if you do a clean install on an already APFS formatted drive, the experience is much improved (at least it was for me). Just remember that after any new install, the drive has to be indexed and Trimmed. Since Trim can't be manually controlled on an APFS drive, it takes some time for this to happen.
Anyway, that's my take on it whether it's right or wrong, I don't know. This is just based on my personal observations of dozens of installs.

I'm on a Fusion drive, which is HFS+, and tried an external SSD also on HFS+.
Yesterday I've read this in 'Insanely Great: The Life and Times of the Macintosh, the Computer That Changed Everything':
Jobs literally made them feel that the quality of Macintosh was a life-and-death issue. At one point in the software development process he was worried about the machine's distressingly lengthy start-up time—almost thirty seconds. He zeroed in on system software programmer Larry Kenyon, who believed he had already squeezed as much speed as possible from the machinery. "Even if it took you three days to make it a single second faster, it would be worth it," Jobs hounded him. "If ten million people use the computer, in one year alone, that's about 360 million turn-ons. How many lifetimes does 360 million seconds equal? Fifty? Would you take three days to save fifty people's lives?" Kenyon wound up shaving not one but three seconds off the start-up time, sparing a hundred extra souls from the Reaper.
This is original Macintosh thirty seconds... I am not a member of the 'bring Steve back from the dead' brigade, but when I read this I did sigh really loudly.
Yeah, that's why I said for me. I know they're are others that are having problems not necessarily associated with APFS and are having slow boot issues. Lucky for me I guess, I'm not in that camp. I did have issues as outlined above but managed to resolve them. HS/APFS is just as fast for me, as any other OS version. In fact, it's faster in my case.
Sadly, not one size fits all here.

Mojave pb 4 just came out. I wonder if this issue is exclusive to High Sierra or not... I can't test it my cMP needs a new GPU to run Mojave, I'll get a new one later this year.
Same here. If that iMac wasn't our main machine I'd be beta testing Mojave by now with the sole purpose of checking the startup time. Might try that from external SSD.
FYI... I found this on another forum:
https://www.tonymacx86.com/threads/long-boot-times-in-high-sierra-2-min.241709/page-5
So maybe there is nothing to "fix" after all and the slow boot time is normal due to how APFS does the trimming... I'd be curious if Mojave works the same way.
