xr_a_y , I cannot really answer yes to that question ... It may indeed be the case. Are you thinking of a particular parameter ? I thought TT was a good candidate because with the used replacement scheme. I think instead of spending significant time on some idea it may be worth rechecking it: if you...

Vivien,

Have you considered that the problem with long TC is not related to hash usage but rather to prunning conditions that are triggered differently in longer controls?
