What became of the append/truncate ideas for queuefiles?
During my internal performance tests I noticed the fsstone program and wondered what became of your ide to use append/truncate instead of generating new queuefiles. From http://archives.neohapsis.com/archives/postfix/2004-07/0991.html Early measurements have shown that disk overhead can be reduced dramatically by using append/truncate instead of create/rename/delete. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de

Early stress tests also demonstrated that Postfix was up to 3 times faster than qmail when relaying small SMTP messages. I'll put the scarce time into finishing postscreen, and worry about queue performance later. Wietse
