So that would mean my disk is not a contribution factor right?
I'm just following this thread because of curiosity.
tmpfs? Or, do you mean ramfs (like Ralf spoke of). I believe there was a
response already made by Wietse with regards to tmpfs that stated:
"tmpfs is backed by the swap file, which is on disk."
Therefore, I would think you would not see a difference.
Yeah I was kind of thinking the same thing. With tmpfs, you can easily set a
fixed size, so postfix sees that and will allow you to place the queue in it
because it appears larger than 1.5 * message_size_limit. However, when I
mount a ramfs, there is no fixed size, so it looks like zero to postfix and
will therefore not accept mail because it seems too small, even though the
space would expand to it allow it.
I haven't figure out how to get around the messages. I tried setting the min
queue free like I mentioned before, but anything over zero I would think
would flag it as too much.
any thoughts on how to mount the ramfs to get a true test of running the
queue in memory?
