# Envoy specific Bazel build/test options.

# Bazel doesn't need more than 200MB of memory for local build based on memory profiling:
# https://docs.bazel.build/versions/master/skylark/performance.html#memory-profiling
# The default JVM max heapsize is 1/4 of physical memory up to 32GB which could be large
# enough to consume all memory constrained by cgroup in large host, which is the case in CircleCI.
# Limiting JVM heapsize here to let it do GC more when approaching the limit to
# leave room for compiler/linker.
# The number 2G is choosed heuristically to both support in CircleCI and large enough for RBE.
# Startup options cannot be selected via config.
