Fellow netlanders, please allow me to ask you a few questions. 1. Where can I get Emacs for Esix, preferably by ftp. I have tried ypig.stanford.edu, but I continuously get timeout errors. 2. I have recently upgraded my system to 16Mb on a 386-25 motherboard. Esix correctly recognizes that memory as reported by memsize. However, if I do a 'sar -r 5 600' it shows freemem = 2803 (which per System V's 2k page frame equals less than 6MB of memory). Where did the rest of the memory go? I expected about 12-13 Mb after kernel and data areas are allocated. 3. I use the Esix FFS. To get maximu performance should I increase NBUF&NHBUF, or FFSBUFFERS (or both). BTW, what is FFSBUFFERS anyways? thanks very much, ...Martin Martin J.

It should, on a well configured system, fairly small, and oscillate around the high water mark you have configured. If you have too much 'free' memory, this means that you have too much memory. If you want to know how much pageable memory you have, look at one of the first lines when booting; there is also, under u386mon, a field that teels you that. I think that the definition of 'free' (uncomitted) memory should go in the FAQ, because alot of people seem to be confused by assuming it is unallocated memory, which usually it is not. -- Piercarlo Grandi | ARPA: pcg%uk.ac.aber.cs@nsfnet-relay.ac.uk Dept of CS, UCW Aberystwyth | UUCP: ...!mcsun!ukc!aber-cs!pcg Penglais, Aberystwyth SY23 3BZ, UK | INET: pcg@cs.aber.ac.uk
