I was seeing upwards of 1000 unlinks per second on the >async filesystem, or 40-50 times faster than a sync filesystem, IIRC. Hi, two quick questions around this... To do what your are describing above, are you saying add something like sync mount -u -o async /usr/local/newsspool sync mount -u -o async /usr/local/newsspool/over.view sync mount -u -o async /usr/local/newsspool/alt/binaries sync . . . and so on... /usr/local/news/bin/expire -s -v1 >>/var/log/expire.log sync mount -u -o sync /usr/local/newsspool . . . and so on... Also, what is the fastrm phase ? Is this a different method than the default used in expire to remove articles ? We are running a 2.1.5 release machine with innd 1.5.1 Thanks, ---Mike ********************************************************************** Mike Tancsa (mike@sentex.net) * To do is to be -- Nietzsche Sentex Communications Corp, * To be is to do -- Sartre Cambridge, Ontario * Do be do be do -- Sinatra (http://www.sentex.net/~mdtancsa) *
