Hello, I am trying to understand the impact of enabling inline J-Flow on the MX104. There are various reports this could impact performance negatively.
My oldest chassis are running 13.3R8. The release notes say about known issues: - Performance degradation of 8 percent is observed on the maximum packet per second supported of J-Flow records exported. PR949965 - Performance degradation of 8 percent is observed on the maximum packet per second supported of J-Flow records exported. PR950101 I don't have access to those PR. It is unclear for me if the performance degradation is on the total bandwidth of the chassis or if there is an 8% slow down on latency. There are various reports saying this feature will also impact BGP convergence times (which are already not great, notably on 13.3): http://seclists.org/nanog/2016/Mar/303 https://lists.gt.net/nsp/juniper/53823#53823 They mention PR836197 which is marked resolved in 13.2R1. Can I then expect J-Flow to not have a negative impact on 13.3R8? Or are there any known issues solved in more recent versions?
