Ethr takes inspiration from existing open source network performance tools and builds upon those ideas. For Bandwidth measurement for TCP & UDP, it is very similar to iPerf3. iPerf3 has many more options for doing such as throttled testing, richer feature set, while Ethr has support for multiple threads, that allows it to scale to 1024 or even higher connections, multiple clients to a single server etc. For latency measurements, it is similar to latte on Windows or sockperf on Linux.
Ethr takes inspiration from existing open source network performance tools and builds upon those ideas. For Bandwidth measurement, it is similar to iPerf3, for TCP & UDP traffic. iPerf3 has many more options for doing such as throttled testing, richer feature set, while Ethr has support for multiple threads, that allows it to scale to 1024 or even higher number of connections, multiple clients communication to a single server etc. For latency measurements, it is similar to latte on Windows or sockperf on Linux.
Ethr provides more test measurements as compared to other tools, e.g. it provides measurements for bandwidth, connections/s, packets/s, latency, and TCP connection setup latency, all in a single tool. In the future, there are plans to add more features (hoping for others to contribute) as well as more protocol support to make it a comprehensive tool for network performance measurements.

### External Server Parameters
```
-m x External server mode - In this mode, Ethr only supports TCP, listening on 9999
Any client can connect to Ethr in this mode. Ethr can also receive data in this mode
This mode is useful for running Ethr server on multiple instances behind a load balancer,
and traffic from clients getting distributed by load balancer to these instances
