Cannot Get WiFly Shield Transfer Rates Above 236 CPS

I am using an Arduino Uno R3 & Sparkfun WiFly Shield WRL-09954 with Alpha 2 (Arduino 1.0) Library

The maximum transfer rate I have achieved is 236 characters per second (ROUGHLY 2400 BAUD)!

I see that others have reported higher transfer rates? I have included my test code below.

I appreciate any advice as to why my transfer rates are so low.

Thanks, Carl
