The only benifits you will really see from using a ramdisk are for things that involve many read/writes. Files that are only read (even if every time) will be cached by the OS (lack of memory and large files aside, in which case a ramdisk is a bad idea anyway), making the ramdisk unnessesary. Things like the MIMEDefang directory are perfect, because
a) The files are created, read, written, and deleted quickly and often, and b) In the event of a system failure, the data in that directory is non-critical. The only other directory we've ramdisk'ed is our AV temp directory, where attachments are written (or extracted) to be scanned, then deleted. Everything else is either critical information (i.e. the sendmail mqueue) or read-once. -Brenden On Fri, 2004-02-06 at 08:54, Peter Campion-Bye wrote: > I moved /var/spool/MIMEDefang to a ramdisk and got a 20% improvement in > scan time (It's a slow old disk in the box) > Before I spend ages experimenting, has anybody found any worthwhile > improvement by moving other stuff to ramdisk, the SA rules for example, (I > expect these are just read once and cached) How about the clamav db? > Is there anything that's read into memory off the disk on every message? > Thanks > > mimedefang 2.39 sendmail 8.12.9 clamav 0.65 spamassassin 2.63 > > _______________________________________________ > Visit http://www.mimedefang.org and http://www.canit.ca > MIMEDefang mailing list > [EMAIL PROTECTED] > http://lists.roaringpenguin.com/mailman/listinfo/mimedefang -- Brenden Conte System Programmer, C&CT Rensselaer Polytechnic Institute (518)276-2540 -- Brenden Conte System Programmer, C&CT Rensselaer Polytechnic Institute (518)276-2540 _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [EMAIL PROTECTED] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
