Back to the Mac: OS X 10.7 Lion Review
by Andrew Cunningham, Kristian Vättö & Anand Lal Shimpi on July 20, 2011 8:30 AM ESTPerformance: Similar to Snow Leopard
Benchmarking Macs is a lot like benchmarking smartphones: there's a huge user experience component and not enough tools to really do a thorough job of evaluating performance. The majority of our OS X benchmarks involve patience and a stop watch and we've redone the whole suite in anticipation of Lion.
Generally speaking, performance under Lion hasn't changed all that much since Snow Leopard. Earlier beta releases of the OS were significantly slower than Snow Leopard, but the final code appears to perform on par with SL regardless of microprocessor architecture.
We tested Lion on two platforms. A brand new Core i7 15-inch MacBook Pro and a much older Penryn Core 2 Duo 15-inch MacBook Pro. We measured performance across a number of applications as well as battery life.
The graph below shows the 2011 MacBook Pro and how its performance fares under both OS X 10.6.8 and 10.7.0. As you can see for the most part performance really remains unchanged:
There were a couple of tests that showed more than a 10% increase in performance (possibly a reflection of Lion's upgrade to OpenGL 3.2 from 10.6's not-quite-3.0) but generally Lion performs no differently than Snow Leopard regardless of the nature of the benchmark. GPU performance also remained mostly unchanged as you can see by the Portal 2 numbers, although the Cinebench 11.5 OpenGL test did go up a bit.
The situation isn't really any different on the older Core 2 Duo MacBook Pro either:
Boot time skyrocketed for some reason (perhaps an artifact of the Lion upgrade on a system with a standard HDD instead of an SSD) but otherwise performance remained mostly unchanged.
Only our iPhoto test showed a greater than 10% increase in performance. Everything else either dropped slightly, stayed the same or showed a small increase in performance.
The seat of the pants feel while using Lion echoes our performance results. While some UI animations seem sped up, most tasks don't feel any quicker under OS X 10.7. Some of the new features under Lion do feel like they require a good amount of processing power. Take the new threaded view in Mail for example. My personal machine is a 2011 MacBook Pro with a 2.3GHz Core i7 and an SSD. Once you get over a dozen replies in a thread just loading the thread easily eats up 50% of one of my Core i7 cores.
What about longer threads? Take a look at what happened when I viewed an email thread with 65 replies in my Inbox:
Three cores at 100% just to load the thread. Note that the loading process took a few seconds, dropping down to only 100% CPU utilization before finally completing the load.

Primarily FAO the AnandTech reviewersThank you for a very timely and useful review of FileVault 2.
The following microblog conversation links to an overview (work in progress) with some unanswered questions. Comments will be greatly appreciated.

And it is a big problem!The removal of Expose and Rosetta are big reasons not to "upgrade" for me both now and for the foreseeable future.
A lot of other things are clunky or ugly or annoying (like the inability to control scrolling speed in System Preferences) ... but those are minor reasons not to "upgrade".
This was a tough review to do, and I love Anandtech, but I think you guys skimmed over some very important negatives. I don't know a single person who is not an Apple employee or stock owner who claims to really like Lion ... come to think of it I haven't yet met an employee who really likes it, so it is pretty much stock owners who are saying it is an upgrade-without-quotation-marks. Although a lot of employees do genuine like the full-screen mode.

I have a circle of nearly 200 fellow Mac users—real, (mostly) unbiased, not-at-all picky or ego-inflated (I'm not suggesting that you are), everyday-if-not-hour-intensive Mac users—and our experience has been 95% positive or enthusiastic. Some are disappointed with the loss of or change to this or that, as am I, and we have to adjust, go As The Mac OS Turns, but not one isn't glad they upgraded. Any OS must continue to be evolutionary or die. Some things go, others stay, but the overall progress is forward. I will take Lion over Windows 7 hands down this or any day. Windows has its features and (of course) fans but I'm not buying, now or ever, unless something goes massively wrong with current OS development.

Thanks for an enlightening test! One thing I wish you had tested was the time to wake from sleep. On my macbook air (with very similar specs to your setup), it seems that waking from sleep takes a couple of seconds more with FileVault enabled. This is pretty significant when you are used to the very quick waking of Apple products...raygos - Wednesday, September 21, 2011 - link
The reviewer complains that Resume can be annoying for the likes of him/her when a clean slate is desired. He/she writes: "I found myself pressing command-W a bunch of times to close windows before I'd press command-Q to quit the program." There is, of course, the shortcut command-option-W to close all open windows in the active application. For mousers, press option while clicking the red "close window" button does the same thing. Gotta save those clicks!dtalari - Friday, October 28, 2011 - link
I am a work-study at a college and we recently bought a bunch of IMACS to make an IMAC Labs for all the students. We also have a few for the staff. We had Snow Leopard installed initially and we were able to connect perfectly fine to all of the servers within our network,however since our implementation of lion the servers don't show up under the shared tab in the finder automatically like before. The computers on the network show up but not the servers. Anyone have any ideas as to why? I figured it has something to do with samba not being implemented as it was in Snow Leopard? Is there any easy way to change a setting? Or do I have to manually add each server to each computer?Thanks
