Description
We're preparing go-livepeer to be flexible on the number of active orchestrators. Livepeer node should work correctly if the n of Os increases from 100 to 1000 or more.
From the initial analysis we identified the following code areas.
| code | seq / par | context | time | 10x time |
|---|---|---|---|---|
client.TranscoderPool() |
sequential | used during startup and before initializing the round | 113s (1.25s each) | 1125s (19 min) |
db_discovery.cacheOrchestratorStake() |
parallel | used during startup | 665ms | 1.4s |
db_discovery.cacheDBOrchs() |
parallel | used during startup and every 1h to refresh | 3s | 3s |
discovery.GetOrchestrators() |
parallel | used during each O pool session refresh | 1s | 1s |
orchestratorwatcher.handleRoundEvent() |
sequential | used after a new round | 20s (0.22s each) | 198s (3.3 min) |
