I have changed MIXDATAROLL in src/osdep/unix/mix.c, and was a bit
surprised when I used mixcvt and got the default filesize.
If this definition was moved to a common include file, say
c-client/mix.h, all mix applications could share the same setting.
Talking about mix filesize, I settled for (4*MEGABYTE), which is
somewhere in the middle of the span that has been discussed previously
on this list.
The reason why I have increased the size is simply to get more
manageably directory listings, but I have no idea what the optimum
filesize is. Too small files will behave like maildir, and too large
files will be like mbx with its poor backup performance.
The optimal setting will of course depend on mail size and volume, but
there should be some sort of best practice which could be used on most
installations.
Has anyone made a serious attempt to see how large the files can be
before they start to affect backup performance, or is everybody
guessing?
