Re: [Gems-users] Ruby_cycles != opal0.cycle ?!

One related question:
opal0.listparam lists configuration related to Memory System:

MEMORY_DRAM_LATENCY                         :               80

Most of them can also be found in ruby. Do I need to unify these
values between ruby and opal? Or it is only useful when opal is used
alone?
