I have that problem with my progress indicator eheh. The kernel is executing so slow, I don't know how do you manage it in JTR but I guess it's something similar. I have a thread that wakes up each 3 seconds and displays the speed based on candidates tried in that time interval. A kernel invocation takes usually 1-2 seconds and it tries say a ndrange of 128*128 candidates. Well speed usually goes around the same 128*128*(1 or 2) value. You can't even measure current speed in a *nice* way. That's why I am thinking of introducing an "average speed" for my program, it would be much more realistic for cases like the rar one :) Content of type "text/html" skipped
