I have done some more investigation and the cause of the slowdown appears to be this bug-fix to eglibc:
http://sourceware.org/bugzilla/show_bug.cgi?id=13658 My (possibly biased) summary of this change is that one user reported inaccurate sincos results for very large numbers so the eglibc library was changed so that *all* sin, cos and sincos functions now use soft maths functions rather than the FPU. Other people are reporting the slowdown as well and there is an eglibc bug report: http://www.sourceware.org/bugzilla/show_bug.cgi?id=14412 No solution seems forthcoming and the bug is only marked as an "enhancement" rather than critical. -- Andrew Bishop -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
