SF5 is relatively slow to render previews on a number of fonts.
Some previews, such as Veneer (a grungy font, relatively complex) take upwards of 5 seconds or more to render a preview. Both complex fonts and dingbats seem to render slow. I keep the font size fixed at what I believe is a reasonable preview size (36px). Previews are generally on fonts that aren’t active (I keep most of my library inactive).
Once the preview is rendered it’s fine for a brief period of time. I can switch away from and back to the preview, but after I’ve viewed a number of other previews and then return to Veneer (or one of the other complex fonts) it again takes 5 seconds or more to generate a preview.
Since I’m partial to more complex fonts (grunge, dingbats) and have a large collection, this is cumbersome for me. I don’t notice this issue when running FontExplorer or Font Book. No font that Suitcase Fusion has issues with appears corrupt, as indicated by either program or SF5 itself.
Unfortunately I prefer the SF5 interface (since Fontcase is retired) and feature set so I’d like to resolve the slowness.
Is there any type of undocumented customizable setting or fix that can be applied? Increasing the cache size, caching the previews as images, etc?
What I’ve tried:
The solutions posted on the Suitcase Fusion Knowledge Base (SF5 recommendations for OS X 10.9)
Restarting the computer
Clearing the font cache using SF5 tools (followed by restart)
Clearing the font cache using Mac Pilot (followed by restart)
My computer: Newer model Macbook Air, 1.7GHz Core i7 with 8GB RAM running Mac OS X 10.9.2
My fonts: I have about 4900 fonts in the library but only 100 or so are activated. I import all fonts into my library, and my library is kept on the same drive as my computer (built-in SSD).
