In general, modern kernels have improvements to the network subsystem. Ubuntu LTS (versions still receiving hardware and maintenance updates) One gigabit per second (1 Gbps) of bandwidth is the minimum requirement to be a host on.Intel NIC’s are a close third, but are considerably cheaper. Not relevant to performance of OoklaServer.Įnsure that at least 1GB of disk is free for OoklaServer and future upgrades.Ĭhelsio and Mellanox have been reported to perform well.
Modern memory bandwidth differences do not have a measurable impact on OoklaServer performance. 16GB minimum is recommended, 32GB to 64GB is more than sufficient to serve a large quantity of clients. However, it does directly correlate to the quantity of clients it can serve. Memory size does not have a tangible impact on per-stream performance. Interrupts will also have to be carefully tuned. If NUMA is not avoidable, ensure that kernel networking threads are allocated to single NUMA node. Single socket board designs perform better than multi socket Overall, IPC is the most important metric for performance with OoklaServerįewer but faster cores are better than more but slower cores.
