High-level benchmarking suite, as part of attempt to speed up Tahoe

Description (last modified by itamarst)

We should have a broader benchmarking attempt, involving:

  • Defining metrics
  • Defining goals

Two aspects:

  • User experience
  • Server-side load

UX is probably more important at this point, but eventually if that's finished server load will become an issue.

Metrics:

  • Latency (single upload/download)
  • Throughput (batch uploads/downloads)

Bottlenecks will be network latency, CPU, network bandwidth. If we've hit point where network bandwidth is the bottleneck, we're done optimizing.

Throughput depends on usage patterns of:

  • tahoe cp
  • tahoe backup
  • sftp
  • Magic Folders
  • Third party backup tools that integrate with Tahoe (duplicaty? duplicati? borg?)

Knobs: number of backend storage servers, network latency.

Might want to get ​https://github.com/tahoe-lafs/tahoe-lafs/pull/1208 merged and then rely on grid manager.
