What became of the append/truncate ideas for queuefiles?

2010-03-29 Thread Ralf Hildebrandt
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.

Early measurements have shown that disk overhead
can be reduced dramatically by using append/truncate instead of
create/rename/delete.

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.
