I am using SLES10 and can't find anything in the manuals regarding the benefits of using DASD in diag mode or not.
Originally I recall that there was a performance benefit for using the diag mode driver under Linux. Is this still the case? Where can I find some information to read regarding this?
There is a small benefit in synthetic benchmarks, but you're probably not going to swap enough to notice. Considering the additional complexity for setting up the diag driver, using the FBA driver might be already good enough. PS When I find a real life application that behaves more like my synthetic benchmark, the recommendation may change again ;-) -- Rob van der Heij Velocity Software, Inc http://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
