TIDE log Benchmark¶
Chunk Sizes and Indices¶
We simulated "scanning" large TIDE log files with varying numbers of entries per chunk and entry sizes. By "scanning" we mean seeking to all CHNK blocks and reading the block headers.
| Number of Chunks | Number of Entries per Chunk | Size of one Entry | Filesize [GB] | "Scan" Time [s] |
|---|---|---|---|---|
| 100 | 100 | 1,000,000 | ~ 9.4 | < 0.002 |
| 100 | 10,000 | 10,000 | ~ 9.4 | < 0.200 |
| 100 | 1,000,000 | 100 | ~ 11.0 | < 200.000 |
