Bitalos

# Bitalostored

  • There are currently several well-known open source storage systems (compatible with the redis protocol), two products (*d* & *i*) with excellent performance are chosen. This benchmark is bases on bitalostored v6.0 and two procudcts (*d* & *i*) newest version.

incr is irrelevant to data size, only needs to be tested once.

# Data

  • Total data size：40GB

  • Comparison dimensions： comand（SET、GET、LPUSH、SADD、ZADD、HSET） x value-size&count（1KB & 40,672,000、128B & 335,544,320）, INCR

  • Comparison standard: QPS on single-core (multi-core QPS / core number), single-core performance reflects cost advantage better.

# Config

  • *d* & *i*
