iiBench measures the rate at which a database can insert new rows while maintaining several secondary indexes. We ran this for 1 billion rows with TokuDB and InnoDB starting last week, right after we launched TokuDB v5.2. While TokuDB completed it in 15 hours, InnoDB took 7 days.
The results are shown below. At the end of the test, TokuDB’s insertion rate remained at 17,028 inserts/second whereas InnoDB had dropped to 1,050 inserts/second. That is a difference of over 16x. Our complete set of benchmarks for TokuDB v5.2 can be found here.
|Benchmark Details: Ubuntu 10.10; 2x Xeon X5460; 16GB RAM; 8x 146GB 10k SAS in RAID10. Each data point is the average insertion rate for the last 2 million rows.|
We developed the iiBench benchmark to measure performance for a use case that occurs commonly in production applications, such as online advertising, social media, and network management.
iiBench simulates a pattern of usage for always-on applications that:
- Require fast query performance and hence require indexes
- Have high data insert rates
- Cannot wait for offline batch processing and hence require the indexes be maintained as data comes in
Note that iiBench was created as an open-source benchmark, which allows others to freely use it, extend it, and contribute their changes back. We originally unveiled the benchmark in the context of a challenge issued at the 2008 OpenSQL camp. Since then, iiBench has been downloaded and used many times, and ported by the community (in this case, Mark Callaghan) to a Python Script.
