A setting of Cache Levels = 3 is the fastest for the diglloyd benchmarks, but Cache Levels = 4 might be a better all-around choice for most users. Your particular workflow might influence the optimal number of cache levels, and with some plugins, using Cache Levels of 4/5/6 might work faster, according to anecdotal reader feedback. Note that memory usage might need to be adjusted downwards if you run memory-hungry plugins which need some extra memory set aside for their own use Photoshop shares the available memory with plugins.

Also, Adobe Bridge is completely non-functional with hardware support enabled on a stock 2008 Mac Pro with an ATI Radeon HD 2600! But redraw speed (clicking layers on/off and/or viewing color channels is troublesome on my Mac Pro when enabled (with both the 20 Mac Pro models). Experiment-it might be worthwhile on other systems and/or might accelerate specific operations. Disabled, it is much smoother and faster. OpenGL is shown disabled, because it degrades redraw performance on my system, a herky-jerky redraw that is intolerable. Testing setup with 16GB memory Minimize the history states and cache levels to save memory Open GL It is shown with Cache Levels = 3, which is the fastest for the benchmarks, but Cache Levels = 4 is often better for all-around use, and can be much faster for commands like Photomerge-it all depends on what operations are being done. This is Photoshop’s Performance preferences dialog.

hide the Histogram palette when running actions or scripts.

A setting of 3 - 6 should work well in most cases, with a setting of 4 being best for all-around use (but slightly slower than a level of 3 for some things). Be sure to set it back to something longer for interactive work If you can work with no history, set it to “1” this makes sense when running actions or scripts repeatedly, where history is not needed. Here are “freebies” to reduce memory usage and speed operations: Systems with 2GB of memory should be adjusted accordingly (and upgraded!).

The preferences discussed here are suitable for any Mac OS X system having 6GB or more of memory, and are often ideal even for 4GB systems, as proven by testing. Photoshop performance preferences PERMALINK Not using Bigger Tiles causes this massive performance hit, which far exceeds performance gains that hardware can provide, particularly on the 2009 Mac Pro Nehalem. Possible exception: if you use files with numerous (50 or more) layers, Bigger Tiles might or might not help, or could be slower. I confirmed with Rob-Art at that same behavior the culprit seems to be the Smart Sharpen function, which runs far more slowly without Bigger Tiles.Įven if the scratch disk is not being used (no disk writes are observed), using the Bigger Tiles plugin is essential. Using Photoshop CS4 11.0.1, I measured these bizarre results with and without Bigger Tiles on both a 2.8GHz 2008 Mac Pro and a 2.93GHz 2009 Mac Pro Nehalem. The Bigger Tiles plugin in particular is absolutely critical to performance in most cases, especially with large files.

Download the Plugins Bigger Tiles is critical

It’s bizarre that Adobe calls these “legacy” plugins, because they have a massive performance impact. Failure to use these plugins results in a penalty of up to 50% on Mac OS X in any “decent” configuration ( over 100% for Photoshop CS3). Use the Bigger Tiles plugin in conjunction with DisableScratchCompress plugin. Plugins that Adobe either doesn’t enable or even include by default are critical to performance! Be clear on this: Adobe’s advice as of January 2009 is stale.
