But I don't have all that kind of hardware, and I don't have the time to do all that much benchmarking. I was primarily looking at what kind of performance hit you take when you get lots of synchronous meta-data updates, and what kind of performance improvement you might theoretically be able to see if you could re-architect your application so as to avoid synchronous meta-data operations whenever possible. That said, I'm willing to collect and centralize benchmarks run on a variety of platforms, but you'll have to use the script I provide to generate the data, and you'll have to give me details about the hardware configuration. If you've made any kernel changes or performance tweaks, you'll need to let me know about those, too. I'll be updating my page at <http://www.shub-internet.org/brad/FreeBSD/postmark.html>; with the new information, and details about what requirements have to be satisfied before I will accept benchmark data from others to be incorporated on the page. -- These are my opinions and should not be taken as official Skynet policy _________________________________________________________________________ |o| Brad Knowles, <blk@skynet.be> Belgacom Skynet NV/SA |o| |o| Systems Architect, Mail/News/FTP/Proxy Admin Rue Col.
