OK. But I was wondering if people at R-core team, especially those who worked on Windows specific aspects, would have in mind some changes they did between 1.7.0 and 1.7.1 than can cause this. Since these changes are mainly corrections of bugs, the list is hopefully not so long... and it could help a lot to have these hints. Thanks very much.
I checked that the slowdown really was happening in "^", which is Primitive and so fairly direct. I couldn't find anything remotely plausible as a cause, though. My first guess was something involving the methods package and my second was a compiler change, so I'm 0-2 so far. -thomas
