Nokia Here Drive performance from microSD on Lumias with 512 MB RAM

[nokia6300]

Anyone here with a Lumia with 512 MB RAM use Nokia Here Drive stored in a microSD card? How is the performance? Any noticeable lag compared to running off the phone's internal memory?
I guess what i'm trying to get at is does the amount of RAM even matter when running Here Drive from a microSD card? Or is it the CPU?
Please let me know.

I do not believe any app can be stored on an SD card yet.

There are no performance issues because apps are not stored on sd card...only map data is stored
