Hi,
In here http://forums.opensuse.org/showthread.php?t=484988 it has been
found that the "libm" library is faulty, makes code run half as slow, in
several distros, compared to previous version. Brute force replacing the
libm library in 12.3 with that of 12.2 solves the issue.
Sample code:
// Version 1.0
//
// Compilation command:
// g++ -Wall -Wextra -O2 check_speed.C
# include <cstdlib>
# include <iostream>
# include <cmath>
using namespace std;
//----------------------------------------------
int main() // Purpose: measure execution speed.
{
const int NX=1000000, NY=8;
double x=-3.3, y=0.0, z=9.4;
int j = 99;

There is still no official response.
I'm posting here on behalf of the people at the forum, they are not
