Performance issues after upgrade/L3-L2 convergence

Has anyone seen any performance issues after upgrading to e2.0.1? We had the need to go from L3 to L2 mode and needed to do a software upgrade. Pre-upgrade our CPE we getting 12-15Mbps/8Mbps. After upgrade/convergence we are seeing 6-8Mbps/4-6Mbps.

Thanks.
Tom
