Howdy, I found out two weeks ago, that one has to switch on soft-updates for ffs manually. I was wondring how many newbies know about this fact, how many of us have done it, how we found out and if there are other tuning facts we should care for. If the above is total gibberish to you, please do the following. Type the command 'mount' on your shell and see if any of your mounted filesystems has 'soft-updates' in the parantheses. If this is not the case, and Your kernel has FFS (look in /sys/<architacture>/conf/GENERIC), please read 'man tunefs' the option to look for is '-n enable'. Also look into /usr/share/doc/smm (I guess that is 'System Manager Manual') under 05.fastfs is more information on the fast filesystem and soft updates. Why You should bother? Have You ever tried to delete a large directory structure, like /usr/ports ? Have You ever wondered why this takes half an hour or longer? Well I did, but I thought I had to live with it ... or change to another OS with a quicker Filesystem. Don't chang OS ... switch on softupdates. Have any of You found other tuning parameters that increased the speed of their machine by an order of magnitude? If so, please tell me, or tell me where to read about it. Sincerely, Robert S.
