## Limitations ## Limitations
* Tested up to 7Gbps/500Mbps asymmetrical throughput with NVIDIA MCX4121A-XCAT. Qdisc locking problem will require integrating <a href="https://github.com/netoptimizer/xdp-cpumap-tc">xdp-cpumap-tc</a> or <a href="https://lwn.net/Articles/840244/">HTB offload</a> feature in future verions to increase bandwidth capacity. * Tested up to 4Gbps/500Mbps asymmetrical throughput with NVIDIA MCX4121A-XCAT. Tested using <a href="https://github.com/microsoft/ethr">Microsoft Ethr</a> with n=500 streams. Throughput is noticably superior with NVIDIA/Mellanox cards vs Intel X710 for some reason.

* Linux tc hash tables can only handle ~4000 rules each. This limits total possible clients to 1000 at this time. Eventually we will rework the code to allow for more clients by linking more hash tables. * Linux tc hash tables can only handle ~4000 rules each.
