Have you considered any alternative to SA? if you have the resources and 
patience try using some other tool with 'Custom Spam Scanner'.. dspam, 
crm114, popfile come to mind immediately though there are others as well.

As for the SA problem on your main machine, are you possibly being 
conservative on resource allocation to SA? like try running a higher 
number of Children or a bigger batch size etc..
