    Posted 07-05-2022 12:03


    Could use some help deciding if i hit hardware limit or i have bad config.

    Device: Juniper srx345-dual-ac, fw 21.2R1.10

    When reading datasheet it states the following:

    Routing with packet mode (IMIX packet size) 2,300 Mbps
    Stateful firewall (IMIX packet size) 1700 Mbps
    IPsec VPN (IMIX packet size) 300 Mbps

    In short i have one uplink to internet and one trunk port with 9 vlans. There is about 350/350 traffic on trunk port between vlans. And 30/15 on ipsec tunnel over internet. Currently i have security policies that allow all traffic between vlans. Not global but seperate one for each vlan.

    Security loging mode is set to event, changing to streaming didnt change much.

    With this simple setup the load is following:
