Sometimes I am ok with it if it improves file i/o response time by say 25% I would love to see Solaris have a feature which allows me to configure the risk I am willing to take with my data. By default it should continue to do what it does right now. As a user if I can change some configuration that makes Solaris follow the file i/o pattern (insecure but quick) as Linux, it will improve my productivity. Right now I am running a J2EE application and it does quite a bit of File i/o and hence my application runs a bit slower on Solaris x86. My knowledge about Unix internals is very limited but as a user I would love to see my Solaris x86 box beat Linux to complete the same task. I am not questioning the validity of current design. > > Do you value your data? Not always. Say on my Java development machine running Solaris x86, I am ok if there is a remote chance that my data is corrupt. I would not like the same risk on a machines running my business critical databases. > > > James C.
