SpamSieve Hanging


I recently upgraded to Tiger and set SpamSieve up again to work with the new Mail. Everything was working fine until I then upgraded to the latest SpamSieve. Now, it hangs on launch whether or not Mail is running and consumes all available CPU.

I sampled:
Sampling process 494 for 1 seconds with 1 millisecond of run time between samples
Sampling completed, processing symbols…

Got any suggestions?

Presumably you mean Leopard? I think if you wait a while it will eventually finish launching. Unfortunately, Leopard has different performance characteristics than previous versions of Mac OS X, with some operations taking approximately ten times longer than before. For some users, this can make SpamSieve slow to launch (many bounces in the Dock) and slow to respond thereafter. Most users will not notice a difference, however. You can make SpamSieve much faster by pruning your corpus. Choose Show Corpus from the Filter menu, sort by Last Used, and delete the words that haven’t been used within the last year. I am working with Apple to find a better solution to this problem.

Yeah, Leopard. Do’h!

I’ve heard that patience is a virtue, but having never practiced it, I guess I’ll give it a try.

Pruned Corpus, Performance Vastly Improved
I deleted everything from the corpus over a year old and it’s substantially faster.

SpamSieve 2.6.6 works around this performance bug in Leopard.

You are so money.
