I am running Cygwin 1.5.25 on Windows XP Professional (Ver 5.1 Build

No longer sure why, but at some point I set my HOME directory to
C:\cygwin
Running cygwin on my machine was quite slow, especially when starting
bash and running man and info (2-5 seconds for each). I also noticed
that nano complained it could not find the file //.nanorc
I changed the home directory in my passwd file to /home/gwyner at which
point the slowdown vanished: bash, man, and info are now fast. the
nano error also went away.
End of observation.
Start of uninformed speculation:
I suspect that this is a variation on the network share cause of
slowdown reported in the FAQ
(http://cygwin.com/faq/faq.using.html#faq.using.slow) -- I suspect that
because HOME was set to / that directory references beginning with the
prefix $HOME/ would resolve to // and therefore be interpreted as a
network share.
It may be that // showed up somewhere in my environment and I did not
see it (although I looked) but if that is not so then it might be worth
flagging the above configuration as another potential source of
problems. (Perhaps more likely with windozy users like me who may not
have the right intuitions or knowledge about where to put the home
directory.)
Your first guess is correct -- many apps use $HOME/filename without
bothering to check that $HOME is / (also, many erroneously assume that
//A is the same as /A).
It's usually a good idea to create a /home tree, with one directory per
user. Cygwin usually does that by default if HOME is not set in the
environment.
