* Make WAL replay benchmark more representative Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com> * Move decoding records from the WAL into goroutine Decoding the WAL records accounts for a significant amount of time on startup, and can be done in parallel with creating series/samples to speed up startup. However, records still must be handled in order, so only a single goroutine can do the decoding. benchmark old ns/op new ns/op delta BenchmarkLoadWAL/batches=10,seriesPerBatch=100,samplesPerSeries=7200-8 481607033 391971490 -18.61% BenchmarkLoadWAL/batches=10,seriesPerBatch=10000,samplesPerSeries=50-8 836394378 629067006 -24.79% BenchmarkLoadWAL/batches=10,seriesPerBatch=1000,samplesPerSeries=480-8 348238658 234218667 -32.74% Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com> |
