I have an Iyonix, and it performed as follows (approximately - I 
didn't take note of the decimal points). Also included, RPCEMu 
prformance here (PC has a 3.4GHz Core i7-2600 processor):

     machine                         secs     frames    relative
                                                        speed, %

     Iyonix                           36       444       210
     W7hp64bit/RPCE0.8.9/4.02         17.57    911       430
     W7hp64bit/RPCE0.8.8/5..17         14.3    1119       529

For an explanation of the speed difference between RO 4.XX and 5.XX
