Thanks Adam and Marcy for your comments. I guess for now I will stick with the fast ethernet. I am running zVM 4.3 and moving to 5.2 in a month or so. Level 2 will not want to work with 4.3 so there is no point in trying.
Once I am on 5.2 and if I still see the same problem, I will open a PMR. Aria On Wed, 18 Jan 2006 09:59:51 -0600 Marcy Cortes said: >We have seem some lousy FTP performance too.
