Thanks for the pointer. I had found it in one of my searches and its discussion of XFS prompted my earlier question asking if anyone was using it on zSeries. It's one of the most thorough papers I'd found. Too many others were quite simplistic and very rarely dealt with SMP environments or scalability.
A couple of other references, of various utility, that I found: Realtime Audio vs. Linux 2.6, Revell Linux Maximus: The RAW Facts on File-systems, Scalzo - http://www.quest-pipelines.com/newsletter-v2/linux2.htm I took a look through the ext3 source code of 2.6.5-7.267 and couldn't see any references to the BKL. Its locks appear to be on queues and ext3_handler_lock. Regards... Neale -----Original Message----- ext3 in current 2.6 mainline doesn't use the BKL anymore. The changes happen during the 2.6 series, I think 2.6.5 and thus SLES9 still used the BKL. If you care about this topic the OLS paper from Dave Chinner has some nice figures on large system scaling of different filesystems: https://ols2006.108.redhat.com/reprints/chinner-reprint.pdf ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
