Collect profiling data

Start acra-server

docker-compose -f benchmarks/docker-compose.pgsql-ssl-server-ssl.yml up

Prepare environment

export OUTPUT_DIR=${OUTPUT_DIR:-/tmp}
export BENCHMARK_NAME=${BENCHMARK_NAME:-default}
export READ_TIMEOUT=${READ_TIMEOUT:-25}
export WRITE_TIMEOUT=${WRITE_TIMEOUT:-25}

• OUTPUT_DIR - where to store profiling data
• BENCHMARK_NAME - will be used as suffix name for collected profiling files. Useful to use different filenames with different config files for acra-server
• READ_TIMEOUT - amount of time how long collect data from acra-server during read command. To collect all data it should be greater than time of script's execution
• WRITE_TIMEOUT - amount of time how long collect data from acra-server during write command. To collect all data it should be greater than time of script's execution

Setup acra-server's config

By default, it configured to use filesystem as keystore, with tls connections and client_id extraction. Use benchmarks/config/acra-server.yaml file to change values.

Setup acra-server's encryptor_config

By default, used to use CryptoEnvelope with acrablocks. You can change it in the file benchmarks/config/encryptor_config.yaml

Run script

./benchmarks/run_transparent.sh

Output example:

run write scripts
run direct write './write.bin 2> >(tee -a default.direct.txt)'
time="2022-02-14T05:36:55+02:00" level=info msg="Took 5.532813209 sec\n"
run acra write './write.bin 2> >(tee -a default.acra.txt)'
time="2022-02-14T05:37:01+02:00" level=info msg="Took 6.512527345 sec\n"
wait 204133

At first, it writes data to database directly and through acra-server.

Second step is read plaintext directly from database and encrypted data through acra-server. For read command time tracking starts after generation data, before read commands.

Finally, you can find profiling data in ${OUTPUT_DIR} folder:

$ ls output/
default.read.pb.gz  default.write.pb.gz 

To view collected data, you need to install pprof:

go install github.com/google/pprof@latest

Generate and open svg in the browser:

go tool pprof -web ${OUTPUT_DIR}/*.pb.gz

Generate svg:

go tool pprof -svg ${OUTPUT_DIR}/*.pb.gz

Look in command-line interactively:

go tool pprof ${OUTPUT_DIR}/*.pb.gz
