It takes a *long time* to create a file in a quarter megabyte directory -- the entire thing has to be searched to make sure the file doesn't already exist. : >Now, I have a question for the FreeBSD gurus out there -- I set : >the fragment size to 512 bytes in order to cut down on disk space : >waste.

The alt.binaries spindle is : really the only one that chews up a lot of disk space, and I have : absolutely no problem trimming its expiry time back. I do that too. But that wasn't what I mean. The average non-binary file is 3K. The default allocation size is 1K. For each article, one can expect half of a block of waste. Thus 1/6 of one's spool space -- on the non-binary groups -- goes to waste. If the block size is halved, so also is this waste. So, by changing this parameter, one saves 8% of the spool space. (In theory. I've done measurements in the past and they're at least in the same ball park.)
