PerfRPC

perfrpc is a tool to test and demonstrate the performance of the retryrpc layer.

Starting a perfrpc Server

# ./perfrpc server -ipaddr 127.0.0.1 -port 53167 -tlsdir ./tls

where tls is the directory where the server should write the TLS credentials

Starting a perfrpc Client

# ./perfrpc client -ipaddr 127.0.0.1 -port 53167 -tlsdir ./tls -clients 1000 -messages 100 -warmupcnt 10

clients is the number of clients the tool should create

messages is the number of messages each client will send in parallel using goroutines

tls is the directory where the client should read the TLS credentials

warmupcnt is the number of messages each client will send to setup the connection and test the connection before running the performance test

What is produced?

perfrpc clients will print a message such as

===== PERFRPC - Clients: 10 Messages per Client: 10 Total Messages: 100 ---- Test Duration: 6.207882ms

illustrating how many clients and total messages were sent followed by the length of time to run the test

Tips for large number of clients

It is important to have enough file descriptors for your clients and servers.

We suggest running as root and setting the ulimit high such as

ulimit -n 1000000
