Benchmarks

These benchmarks were conducted using gamache/httpc_bench.

GET requests lasting 10 ms are performed.

Clients ran on AWS m5.4xlarge (16 vCPUs, 64 GB RAM) running Ubuntu 18.04.

The server ran on a separate m5.4xlarge, configured identically.

Clients:

• Mojito 0.3.0 (Mint 0.2.1)
• Buoy b65c06f
• MachineGun 0.1.5 (Gun 1.3.0)
• Dlhttpc 1072652
• Hackney 1.15.1
• Ibrowse 4.4.1
• Httpc (OTP 21.2)
• Mint 0.2.1, without pooling or keepalive, as a reference client.

Current results (2019-05-15)

This benchmark was run after optimizing the servers for high-concurrency tasks by executing ulimit -n 12000000 to increase the allowable number of open files. This configuration is very different from the default ulimit -n 1024 on Ubuntu systems.

The enhanced configuration showed that Buoy and Gun really shine when they are allowed to stretch their legs. Mojito performs well but has catch-up work to do! Likely areas of improvement are in pipelining (we use none, currently) and concurrency-friendly connection checkout in a similar manner to Shackle or Dispcount.

The original benchmark

With server specs as above, except using Ubuntu's default ulimit -n 1024. This benchmark rightly showed that Mojito is fast, but wrongly showed it being faster than Buoy. It does tell us that Mojito excels in resource-constrained environments, or where configuring custom ulimits is not possible.
