Slower searchers such as Hiarcs7 will take more time to fill the hash table. The constant in the equation will need to be reduced for a slow searcher like Hiarcs7. The equation is probably not terribly accurate as the type of processor also needs to be considered. For example a Pentium 200 MMX is faster than a Pentium 200, hence a larger hash table would be required for the MMX than what the equation would predict. Regards Steven Juchnowski
