I've posted my simplistic benchmark results at http://coda.wikidev.net/Small_file_performance. Write-back caching was disabled as calling 'cfs wbstart <dir>' reliably freezes venus. Disk i/o was extremely high during creation/deletion of 1000 very small files, not sure if this is related to using xfs rather than ext2.
Are there ideas or plans on how to improve write performance? Jan indicated in an earlier post [1] that the main reason is the synchronous operation with fsync and possibly tcp handling. I'm trying to install OpenAFS as well to do the same benchmark, its support for 2.6 is a bit lacking though. 1.) http://www.coda.cs.cmu.edu/maillists/codalist/codalist-2003/5021.html -- Gabriel Wicke
