Hello, enabling OpenMP slows down the test-suite on my maching significantly. Compiling with gcc 4.10.0 and O3 on my i7-2760QM@2.40GHz I get the timings below (left = OpenMP enabled, right = disabled), using all 8 threads. Am I doing something wrong here, does anyone gets a different picture ? If no I wonder, should we better remove the existing #pragmas in the fd and tree part of the library again ?
