fuzzyocr slowing up my server

[pinoyskull]

I've been using fuzzyocr plugin for some time now and I think I noticed 
is its high cpu/memory usage resulting on delayed delivery of mails. The 
server is serving 2000+ clients.

The server is a P4 2.6Ghz, 1GB memory running on FreeBSD 6.0. Should i 
upgrade the memory to 2GB or 4GB? Will it fix the problem?

I need your input guys. Thanks and Merry Christmas.
