Putting directories that you use frequently earlier in your path is sometimes a help for long paths. If directories you use frequently are network paths, this may not prove helpful though. >By the way I made further tests and I found that NT network directories are faster >than Samba network >directories. I use Samba 2.0.5. Is there any tuning to do with Samba to improve my >CYGWIN environment >performances. Not that I know of off-hand. You can check the email archives (or the source! ;-) ) for possible settings for the CYGWIN environment variable that might help here. I seem to recall that there is one for SAMBA specifically but I forget the issue it was targeting. Just a guess but I suspect your performance differences between your NT machines and those accessed through SAMBA are based on network/hardware differences. I could be wrong. There are allot of potential differences here. You can check the SAMBA sites for SAMBA tuning information of course. >Thank you again for helping >> >> >> >>Larry Hall <mailto:[EMAIL PROTECTED]>[EMAIL PROTECTED] >>RFK Partners, Inc. <http://www.rfk.com>http://www.rfk.com >>838 Washington Street (508) 893-9779 - RFK Office >>Holliston, MA 01746 (508) 893-9889 - FAX >> > > >-- > >Arnaud GAND >SETI Ingénérie Conseil - Le DORAT >tel 05 55 60 65 59 >fax 05 55 60 67 02 -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
