Did you check the page-outs, as suggested?
Yes--forgot to include that. Despite the large (?) number of
swapfiles, there were no page-outs during the period when I first
checked things. Since rebooting, it is still on 1 swapfile, and still
have not yet had a pageout.
I also haven't experienced the big slowdowns that started this whole
thing. Of course they go away after I go to all this trouble to look
into it (and after you all so helpfully spent your time helping me) :)
When you have a slowdown, try: check out the virtual page-out number,
change between applications, and check page-out number again. If it
increases a lot, then it is probably too little RAM. Too little RAM may
slow down the computer with a factor as large as 100 (ratio between hard
disk and RAM speed) - I have seen it. Same if certain operations within a
program becomes slow. Some programs though have buffering problems, that
may slowing it down, like in Safari if it is open for a couple of days,
especially when looking on pages with much graphics; then a fix is to
restart it. I have noticed that especially various video and audio media
players can use much CPU time even when run in the background or hidden.
So check CPU time too. (As someone told, both CPU time and pageouts can be
checked in Terminal typing
top -uR
quitting with "q".)
If you can exclude this, it may be something else :-).
