What is the speed difference between popular ICD units?

ICD Timings
PIC18F4520® MCU Load Time* Single Step Time**
MPLAB® ICD 2 (USB) 7 1.3
MPLAB® Real ICE™ 5 0.1
CCS ICD-U40 18 1.9
CCS ICD-U64 4.5 0.4

* Times are in seconds, loading a full PIC18F4520 ® MCU on a 1 GHz PC.

** Times represent how long it takes in seconds to execute a single step command on a 1 GHz PC, where a single step is the time it takes the program counter to increment one address. For all cases, the software was set to read all memory on each single step.
