thx for the reply , but I wasn`t talking about the configuration , but about the performance,

What specific questions do you have about performance?

does the microSD can handle the web-proxy cache feature ?

how is the performance in general , is it the best choice for a mid-sized coffee-shop ?

Yes, I am also very interested in this feature. And which MicroSD card (class 2,4 or 6 …) …
A 16GB card should be fine I presume.
I saw some CPU issues in another posting: http://forum.mikrotik.com/t/450g-microsd/35536/1
