Agreed there, I did have to install the compiled regex package to get SA speeds up enough to handle the increased load (my server is not even close to yours in performance but I did drop SA time from 10-30s to <3s). Don't get me wrong, I liked GL but there are a number of big ISPs that have quite long retry timeouts (for some reason, sympatico comes to mind) and it got to be too annoying. who knows, all the code is still there and I might switch it on again in the future.
