Maybe we can have one thread people can just search instead of multiple ones. For lag, smoothness, etc on supported Macs. I hope this will encourage people to post freely. Anyone know how it is on 2012 retina MacBook Pro?
 
My 2012 MacBook Air seems to be running faster on DP1 than it was on High Sierra 10.13.6 Beta 1. High Sierra I felt like slowed that machine down to a snails crawl but messing around with it for the last hour on Mojave, it seems fast again. Could be the whole Metal thing, maybe the OS is built around ti now which is why so many Macs are no longer supported.
 
The word cloud included "Improved hard drive performance", which I assume refers to APFS improvements (unless they literally mean HDD-specific improvements?).

I wonder if someone can vouch for VMware being faster on 10.14?
 
MacBook Pro 2017, running really well for a DB1! It was a little hot at the beginning but it's basically back to normal now. One thing that I have noticed, however, is launch pad really laggy. So far very impressed with performance for the last 2 hours I've been using it.

EDIT: also, there is a slight lag when dragging around windows

runs very smooth on 2012 non-retina MacBook Pro with 27" iMac as target display

GUI is much less smooth on my 2015 13" rMBP. But it was the same way with HS and even Sierra betas, they did bring the perfomance to a good level in the end.
 
How is it on a 5400 rpm HDD iMac? One feature that specifically was shown was Improved Hard Drive Performance and given that MacOs performs quite badly on spinning hard drives, any improvement is welcome.

I hope is the latter. Mac OS performs quite badly on spinning hard drives since Yosemite.
 
Late 2013 rMBP. Running a little sluggish. It's expected with the beta so it's not bothering me. The new iOS apps - News, Home, Stocks, Voice Memos run a little slow and choppy.

I measured SSD performance (same SSD, APFS volume created with Mojave installer) using SpeedTools QuickBench: macOS Mojave is not faster. no matter what block size, the exact same speed was shown.
 
Performance is fine. However, I cannot open any of the new apps (News, Stocks, Memos) and I get a UIKit error. Not sure if anyone is having the same issue?
 
The Messages app has frozen on me a couple times, but I've been a big fan overall so far. Not experiencing any of the kernel panics and laundry list of incompatible apps that usually accompany a developer beta 1.

They didn't really gloat about it, but it seems as though they put some effort in to performance and stability on the macOS side of things also.

I'm running it on my 2015 rMBP 13", unable to run it on my iMac since its for work.
 
To all europeans with supported devices: Is News already available on the European Union?
On iOS, News was only for USA, and maybe some other country, as far as I know

I'm in the UK and have news on iOS 12 and macOS Mojave. On my mid-2012 non-retina MBP (16GB RAM, Samsung Evo 850 SSD) I'd say Mojave runs slightly smoother and faster than High Sierra. I do have the slight laggy feel with News (as described by someone above), but nothing major.
 
I'm in Czech Republic which does not have access to News app in iOS but I DO have it on Mojave. It's incredibly slow and jerky on 2015 13" rMBP though. Like really, really rough.

News is only available in USA, UK and Australia.

These things rarely touch low level benchmark scores (unless it's a new API like metal), I imagine it's more real world like when a hard drive (very easily) reaches 100% IO, how does it handle that load so the user doesn't pull their hair out.

Be very curious for high quality in depth testing of Mojave on rust drives when the final build is out.

Running well so far on my MacBook Pro 13" (Mid-202, non-Retina) with 525Gb Crucial SSD and 16GB RAM.

Google Maps was feeling very laggy under Safari earlier, but that's about the only performance issue I've noticed.

Also, as previously noted, the News app doesn't feel as smooth as other applications yet, but that's to be expected at this stage.

Exactly. People need to stop using synthetic benchmarks to measure speed of OSes. You'd probably get very similar Geekbench scores on Leopare and Mojave running on the same machine. Real-world performance would be completely different.

Hardware benchmarks are best used when trying to compare components prior to purchase. They cannot be used (as they so often are) as a way to compare products spanning across multiple OS’s (iOS vs Android).

A Core 2 Duo might blaze through Windows XP, but struggle on Windows Vista, yet wield similar benchmarks across each OS.

The best type of benchmark, although not very scientific, is a staged walkthrough of various apps / tasks. This is what iApplebytes uses for iOS devices.
 
Nice to hear that Mojave feels a bit smoother than High Sierra. I'm getting bits of lag and dropped frames in High Sierra on a 15" retina 2012. Things like switching Safari tabs or Spaces, there's a noticeable delay or jerkiness to the animations. Are other retina 2012 15" users experiencing this on High Sierra as well, or just me? I've just gotten this machine so I haven't grown with it. I've been using a 2016 15" which is buttery smooth so the difference is very noticeable. Both machines are on 10.13.5. I used Migration Assistant from the 2016 to the 2012 so maybe that brought over something the 2012 doesn't like? Is it worth restoring the 2012 and setting it all up manually or is the jerkiness just par for the course on that machine and I should just live with it until Mojave is out?

Yes, it's a known issue with High Sierra on the 2012 - 2013 MacBook Pros with Nvidia graphics. Frustrating that Apple has done such a poor job optimizing the OS for slightly older (but still supported) hardware.

Mojave is better, but switching Spaces with multiple apps open still stutters.
