This is not expected behavior, particularly with the hardware you're using; I can open and search a 20,000 item file with only minor slowdowns. If you can reproduce a beachball, take a sample (or 2-3 samples) with Activity Monitor and post the output. > I'm hoping to deal with this by splitting this bibliography up into a > few different files.

Unfortunately, it's impossible to make performance improvements without specific information (e.g. samples). Random guesses about bottlenecks by developers and users alike are typically wrong, and lead to much wasted effort. -- adam ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Bibdesk-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/bibdesk-users
