Apple, this is ridiculous.<\/p>\n<p>My workplace purchased a fleet of 5400 RPM computers for some basic typing and Web browsing needs. Every single one of them is this way. Opening Microsoft Word literally took over a minute before the icon stopped bouncing in the Dock.<\/p>\n<p>Listen: I get it &mdash;&nbsp;I understand that some people don&rsquo;t need top of the line computers. But regardless of who uses this computer, this is a poor user experience.<\/p>\n<p>I used to be able to tell friends that even a low-end Mac would be a good experience. That they could get a base model and it would still be decent. That Apple doesn&rsquo;t sell a &ldquo;bad&rdquo; computer; rather, they have &ldquo;good, better, best&rdquo; tiers. That is not the case anymore.<\/p>\n<p>And this iMac isn&rsquo;t even the base model! Insane.<\/p>\n<\/blockquote>\n<p>I spent many years using Macs booted from hard drives, including a 4,200 RPM one in a MacBook Pro. You would think a modern iMac would be faster than that, both because of the CPU and because the larger capacity drives have a <a href=\"https:\/\/macperformanceguide.com\/Storage-WhyYouNeedMoreThanYouNeed.html\">higher data density<\/a>. But it sure seems like macOS performs worse than it used to if you don&rsquo;t have an SSD.<\/p>\n<p>Is this because there are more background processes that are accessing the disk? If so, is there anything that can be done about that? Within my apps, I try to limit concurrent operations on the same physical disk. You might think GCD would do something like this system-wide, but <a href=\"https:\/\/mjtsai.com\/blog\/2014\/05\/12\/how-to-efficiently-read-thousands-of-small-files-with-gcd\/\">it doesn&rsquo;t<\/a>.<\/p>\n<p>iMacs now use 2.5-inch notebook hard drives, presumably to make them thinner, but that doesn&rsquo;t explain why Apple has chosen to use <a href=\"https:\/\/www.reddit.com\/r\/apple\/comments\/6flalj\/the_215_inch_imac_still_ships_with_a_5400rpm_hard\/\">5,400 RPM<\/a> models rather than 7,200.<\/p>\n<p>There are also software bottlenecks even on an SSD. Some customers have reported Mail on Mojave taking over a minute to launch, seemingly related to FSEvents monitoring a <a href=\"https:\/\/mjtsai.com\/blog\/2018\/10\/25\/mojave-fixes-quicklook-cache-vulnerability-with-a-datavault\/\">DataVault<\/a>.<\/p>\n\n<p>Update (2018-11-27): <a href=\"https:\/\/twitter.com\/colincornaby\/status\/1067537366154305536\">Colin Cornaby<\/a>:<\/p>\n<blockquote cite=\"https:\/\/twitter.com\/colincornaby\/status\/1067537366154305536\">\n<p>It&rsquo;s really frustrating when you boot Windows from the same Mac and it&rsquo;s running pretty well with a slow disk<\/p>\n<\/blockquote>\n\n<p id=\"poor-mac-performance-without-a-ssd-update-2018-11-28\">Update (2018-11-28): <a href=\"https:\/\/twitter.com\/_jlfischer\/status\/1067541695183544320\">Jonathan Fischer<\/a>:<\/p>\n<blockquote cite=\"https:\/\/twitter.com\/_jlfischer\/status\/1067541695183544320\">\n<p>I bought a 2017 4K iMac a month or so after they launched, and I opted for the Fusion drive.

The fleet of 2015-era iMacs at work have also gotten really awful, mirroring what others have said in the linked stories, so they&rsquo;re getting SSD upgrades, as well.<\/p>\n<p>Apple moving to an all-SSD future is completely reasonable, but making machines that are new or still under their factory warranty run worse than they should seems like a bad look, even if MacBooks are way more popular.
