Hi! Sorry that I´m bit late answering your question.
In all 3 versions (2008/2009/2010beta) I use the following options:
Use as little cpu power as possible not checked
Skip deep directory structures to improve speed not checked
skip larger files than 100MB to improve speed checked
disable cross-drive checking to improve speed checked
skip system files to improve safety not checked
The files that are compared are mainly jpeg´s. But at my computer it´s allways the same: in the 2008 version for 105000 files it takes about 6 minutes and for the 2009 and 2010 beta versions considerably longer (to be honest after fifteen minutes I quit that and use the 2008 version)
Any idea?
Kind regards,
