With OS X 10.11 'El Capitan' Apple is looking to squeeze more performance from existing Mac hardware.
Based on Apple's internal testing, OS X 10.11 will offer up some significant increases in performance when it comes to app launches, app switching, performance of the mail app, and opening PDF documents.
These are idealized performance increases so real world performance may vary, but it's clear that Apple is looking to do more with less.
OS X 10.11 also brings the Metal core graphics technology currently found on iOS to the desktop. According to Apple's figures this will bring up to 50 percent faster rendering performance to apps and up to 10 times better draw call performance.
One company that's already testing Metal on OS X is Adobe, and the company claims that it can get performance increases of up to eight times using Metal, and is keen to see what it can do for Creative Cloud users.
As someone who's been using OS X 10.10 since it was released, I'm looking forward to any performance increase I can get. OS X 10.10 has always felt slower on my hardware compared to earlier versions, and while it's not a deal-breaker, it's good to see Apple giving it some attention.
