I noticed this question had gone unanswered for a bit so wanted to offer a little help.  But I have to say I am not a current AutoCAD user (used it a number of years ago), and don't have personal experience with your problem.  However as an expert interested in Windows and scripting in general I did a little research.

It sounds like when AutoCAD was ported to a 64 bit version that the way they had to approach VBA caused some major performance issues.  You already know that.  Looking on some of the Autodesk support sites it seems like you have a few choices.

(1) Uninstall AutoCAD 64 bit and install AutoCAD 32 bit.  This seems to reslove the VBA performance issue, but naturally other AutoCAD functions will be slower.

(2) Convert your VBA routines to VB.NET.  Performance will be great there, but there is a learning curve to get to VB.NET, and it is more complicated.

(3) Convert your VBA routines to Visual LISP.

Sorry there isn't a simple solutions, you may want to post on some of the AutoCAD specific support forums and see if you can get additional information and help there.  A few links below that might be helpful.
