1. What was the round-trip time (RTT) or latency of a message between one gRPC client and one gRPC server?
2. What was the throughput (i.e., requests/sec or messages/sec) of one gRPC sever when one gRPC client is running and when two gRPC clients are running?
3. A brief but detailed explanation of how you went about measuring the latency and throughput. You should include any decisions you made (e.g., wall clock vs. CPU clock, synchronous vs. asynchronous RPCs, etc.).
4. Compress all your relevant source code (only the files you actually created/modified; not the whole gRPC repository!) along with the PDF in a zip archive or tarball and submit to CatCourses.
a. The files you modify for this lab will probably be greeter_client.cpp and greeter_server.cpp, though it depends.
