Maybe the relatively fast context switching on s390 helps to mitigate the issue, but it would be something to keep an eye on. It does not have to be a show-stopper, but it would make a difference for your system design. Looking at the following quote from the UnionfsFuse web site, this developer clearly comes from another world. "Compared to kernel-space solution we need lots of useless context switches which makes kernel-only solution clear speed-winner (well, actually I've made some tests and the hard-drives seem to be the bottleneck so the speed is fine, too)" Rob -- Rob van der Heij Velocity Software http://www.velocitysoftware.com/ ---------------------------------------------------------------------- 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
