Observation: setting HOME to / can lead to slow cygwin
I am running Cygwin 1.5.25 on Windows XP Professional (Ver 5.1 Build 2600 Service Pack 2) 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.) --George Wyner -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

(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.
