Not to pick on you, Kirill, but rather in general: That entirely depends on the optimization level and the configuration. I measured a small degradation (<5%) at -O3 on ia64. So, let's find out how the 25% compile-time performance improvement was achieved before we use it as an argument in any discussion, shall we? -- Marcel Moolenaar USPA: A-39004 marcel_at_xcllnt.netReceived on Mon Apr 25 2005 - 14:23:54 UTC
