Need Advice - Forms 92100 errors and Excessive initial load times

 I apologize for the high level of this information – just trying to get the ball rolling and seeking some (hopefully patient) advice; I can fill in the blanks as we go. Recently we added approximately 30 more users in several new separate branch locations connecting to our 11g database via 10gR2 Forms. All the new users have the same version of Java, the same browser, the same OS, and the same connection methodology (T1 MPLS).  We have two issues mainly isolated to the new users, not necessarily affecting the existing (bulk or our) users:  Issue 1: Login consumes huge amounts of bandwidth, overwhelming the MPLS T1. Network analysis shows about 2 MB of data for each login attempt (which is one very tiny Form that solicits an ID and password).   When several people at a location try to login simultaneously the T1 is overwhelmed and problems occur.   The only solution I find seems to be using smaller JAR files.  Is that all I can do? No way to cache the Java libraries locally?
