+# Optimizely Go SDK Examples
+
+Examples of client instantiation, datafile management and Feature enabled are provided in main.go 
+
+# Profiling
+
+Prerequisite:
+1. `go get github.com/pkg/profile`
+2. DATAFILES_DIR env var has to be set to point to the path where 100_entities.json is located
+
+To get profiles:
+* CPU profile. Execute: `go build -ldflags "-X main.ProfileMode=cpu" benchmark/main.go && ./main_profile_feature`. It will create cpu.pprof file in your current directory. Then run: `go tool pprof -http=:8080 cpu.pprof` and profile cpu usage using web browser.
+* Memory profile. Execute: `go build -ldflags "-X main.ProfileMode=mem" benchmark/main.go && ./main_profile_feature`. It will create mem.pprof file in your current directory. Then run: `go tool pprof -http=:8080 mem.pprof` and profile memory using browser.
