Since both the x50v and x51v have about the same amount of available memory, then both should be configured with the same amount of code paging pool memory. According to Microsoft, the code paging pool is a 1 to 6 meg block of memory that is used to cache program code. So the initial slowness may be due to the axim copying the program to cache and the subsequent speedup is to due to the program being in the cache already. Interesting enough, since the x50v's rom is NOR while the x51v's rom is NAND, the x50v should not need to copy rom programs to cache to run but can use XIP (execute in place). So if Dell configured the x50v wm5 rom correctly, starting oem supplied rom programs such as ie or mobile word should be faster on the x50v than the x51v. Unfortunately, user installed programs, either in BIS or storage card, cannot use XIP and must go through the copy to ram-before-running step. Anyone notice a difference in speed when running an oem program in rom versus a user installed program?
