# Proxy build and runtime

# This is intended **DEVELOPMENT ONLY**, i.e. so that proxy developers can
|
|
# easily test the proxy in the context of the larger `linkerd2` project.

|
|
# When PROXY_UNOPTIMIZED is set and not empty, unoptimized rust artifacts are produced.
|
|
# This reduces build time and produces binaries with debug symbols, at the expense of
|
|
# runtime perforamnce.
