Adobe Plugins for Photoshop CS5 Performance
The Adobe download page for the CS5 plugins is at http://kb2.adobe.com/cps/828/cpsid_82824.html.
The Mac download is here.
Analysis of the plugin behavior is pending.
In Photoshop CS4, this plugin was strongly advised.
With enough memory there is no benefit to this plugin in Photoshop CS5.
Analysis of behavior under other conditons is in progress.
DisableVMBuffering plugin / ForceVMBuffering
I observed no difference at all with the DisableVMBuffering plugin on my 3.33GHz Mac Pro Nehalem with 24GB memory and the diglloydMedium benchmark.
