There are two extraneous pow() computations in solver_mean_direct.cpp in the venkatakrishan limiter at lines 4395 and 4414.

/*-- Get limiter parameters from the configuration file ---*/
dave = config->GetRefElemLength();
LimK = config->GetLimiterCoeff();
eps2 = pow((LimK*dave), 3.0);

You take about a 20% speed hit from this. This computation should be outside the edge loop.
