Performance: 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.

    I just installed Lion on a OCZ Vertex2 SSD and it still doesn't support TRIM. I guess support for this feature is limited to stock Apple SSDs only.

    Thanks for the reply. It is a shame that there still is no TRIM support.

    In the mean time I would recommend checking out a 3rd party program called TRIM Enabler:

    Though the program is designed for Snow Leopard it works for Lion, but they are making a new version for Lion.

    I love how these diehard Apple fans are trying to resolve their discomforting feelings of exorbitant expenditure to Apple by

    A: Unreasonably denigrating other competitive alternatives.
    B: Exaggerating the usefulness of certain proprietary tools.
    C: Empathizing with the company's goals/missions/values

    All to resolve the realization that they are paying more money than what they are getting, which is...

    A totally outdated OS made to look streamline
    A pretty cool looking computer that uses tunnel fans (which are extremely loud) and likes to overheat.
    I used Snow Leopard on my Mac Mini for about 2 months and hated it. I think people force themselves to like OSX just because their laptop looks cool.
    Horrible graphics speeds. Their BEST video card that you can fit into a their $4500 Mac Pro, is a ATI 6500 series, which is like a 100 dollar card, and offers pathetic performance for gaming--I had a 6950 2gb and that was barely enough. You can argue that Mac pro's should be used for graphics design and other things and not gaming. If that's the case I don't see why they don't put a FireGL or other designer cards in. In any case, who buys a $4500 computer that comes with a bullcrap video card? Some people are IDIOTS.

    Edit: A $170 dollar video card, 6870 1gb...Which is a complete piece of garbage card that is 30% slower than the 5970 1gb. Guess how much the upgrade is? $200.

    Macs don’t seem to be the right choice for you. That’s alright. Just don’t claim that everyone else has the same needs as you.

    The test with the SSD is intriguing but there's a possibility that the FileVault performance hit might be less in the case of a conventional hard disk.

    Reason: hard disks are slower than SSDs, so there would be more idle states in which the OS could be performing encryption/decryption tasks.

    Worth a spot-check.

    That's a great point. I'd also love to know if the performance impact decreases with an HDD.

    What annoys me is the fact that the recovery partition doesn't keep a copy of the Lion installer for instant re-installation - and with a bit of Apple magic even a copy that updates as the OS updates.

    A download each time is a possibly expensive prospect considering we all have data caps of some kind.

    It also turns a reinstall into a shockingly long 4 hour job which is a major pain.

    Small detail, but in the review you said you could only launch Launchpad by clicking the dock icon or using spotlight, but you can also set it as a hot corner. This is what I personally do... top left corner set for Launchpad and I can quickly get in and out of it to find my apps and utilities.

    I'm not suggesting it's quicker than using an apps stack on the dock... actually, its the exact same. But it definitely is faster than clicking the Launchpad dock icon or using spotlight to launch it.

    Does anyone know if Lion extended trim support to 3rd party SSD's, instead of only the ones apple provides ?
