Welcome.
First thing is sorry about my english.
I would buy one of the models Mikrotik, RouterBoard 750 or 750gl.
In the Webstore and find this kind of Differences Between this models.
First is memory:
RB750 has 32 MB SDRAM. RB750GL has 64 MB SDRAM.
Second is speed of ports:
Ports speed:
RB750 - 5x Ports Ethernet 10/100 Mbit / s Fast Ethernet with Auto-MDI / X
RB750GL 5x Ethernet Ports 10/100/1000 Mbit / s
Differences Between ports speed its clear for me(may be outside „with Auto-MDI / X”
But this is not a point.
I would like to find out what do I get widh 32 MB SDRAM more in RB750GL,and increases efficiency with target network.
I have bandwidth 60 Mb/s and 15 users what i should buy rb750 or rb750GL?
What is the benefit from more SDRAM in RB750GL?
I greet.
