18. Thursday, October 10, 13
19. systems • digital ocean $5 / mo plan • digital ocean $80 / mo plan • linode $20 / mo plan • linode $80 / mo plan Thursday, October 10, 13
20. focus on core • evented app • single processor • cpu bound • same story for redis Thursday, October 10, 13
21. we’ll base core perf on redis • redis-benchmark • 2.6.16 • $ redis-benchmark -q Thursday, October 10, 13
22. redis GET results lin-20 lin-80 so-5 so-80 28,985 37,174 67,114 82,644 Thursday, October 10, 13
23. Postmark • file system transactions • generally used to simulate email systems like postfix • generate 50,000 files of between 1 and 10KB, perform 100,000 transactions Thursday, October 10, 13
