After some testing it seems to work ok. The performance gain is about 15% on i386 and sparc64. Other systems haven't been tested yet, but I encourage all of you to test and give feedback. There's a weird bug in SMP systems that I haven't been able to fully track down. Sometimes gbde will fail to attach on systems with more than 1 CPU. Fortunately, it's harmless. Fetch the patch from here: http://tinyurl.com/cx5f The patch should apply cleanly on any recent -CURRENT. Sorry, it won't work on 5.0-R It's my first patch against the kernel code, so expect a few non-BDE-complying mistakes. Sorry for that. Thanks, Jason -- Jason Stryker jstryker@petml.com -- http://www.fastmail.fm - IMAP accessible web-mail
