I can just about make it on 2xXeons at 3.0GHz, HT enabled, 4GB RAM. But the new "Core 2 Duo" stuff is tons faster, is dual core but no HT yet, has better cache, faster memory bus... costs more. Some big NUMA hardware after that, I will guess the new cheap point is o/c Core 2 Duo 6700, and will finish in about 7 min. Patience is a virtue. -- Bill Davidsen Obscure bug of 2004: BASH BUFFER OVERFLOW - if bash is being run by a normal user and is setuid root, with the "vi" line edit mode selected, and the character set is "big5," an off-by-one errors occurs during wildcard (glob) expansion.
