Hi Andrew -

I'm currently using the following with an RB2011UiAS-RM on a 1Gbps/100Mbps link:

Just a quick estimate based on RRD in Zenoss, CPU is sitting at around 95% idle _most of the time_, after about 15 months of history. I used this little box as my home router w/OPNSense but once I moved to gig fiber I couldn't pull more than 450mbit w/o any firewall rules and upgraded to the RouterOS device. I fluctuate between ~15-25k hosts depending on uptime and probably max out around 2-3k flows. Using mysql, historical searches can become problematic beyond 2 weeks even with SSD+8GB ram.

    for ARM-based solutions I think the RPI3 is a good option if you
    can add external storage on USB as the MMC is not suitable for
    writing long term data. On the RPI3 if you need the second
    ethernet you need to use a USB-based adapter


​Luca,

At what level of traffic does the RPI3 start to max out, please? I understand that number of flows and packet size are important here, but this is a pretty small development office with a ~ 10-100Mbps downlink and fairly standard traffic profiles.

Many thanks for your quick response.

Andrew​
