There should be a reported slowdown of perhaps 20% (earlier I said 10% but that was too low) from K3 to K4 due to changed node counting. But based on the above reports, on the 32 bit version the slowdown is far greater than this, so something seems wrong. I would recommend holding off testing of the 32 bit version until we have time to investigate.geots wrote:Werner wrote:Here on my Intel (no SSE) I have:

Komodo 3 is much faster
Werner, I cannot dispute what you show, but in an email not long ago, Don told me not to worry, it was just as fast as Komodo 3- just measuring more accurately. This is not from me- but I trust what Don tells me. (And what the hell do I know anyway)
Best regards,

Don- Don't understand Komodo 4?? A bug??
