Performant Java hash functions – today’s Java hash problems and our solution
Today, core Java APIs lack high quality hash functions, and 3rd party implementations provide sub-optimal performance. As non-cryptographic hash function are important building blocks of software, this is a major bummer for developers.
Generally, the selection of available hash functions is plenty, and in the last decade, many new hash functions emerged with very good hashing properties. Surprisingly, the core Java API just still offers Adler32 and CRC32, which were designed as checksums many years ago. Of course, there are many hash implementations available outside of the core Java API. However, Continue reading→
greenDAO 3.1 released
4 weeks ago we released greenDAO 3.0 introducing @Entity annotations as an alternative to the generator project. We noticed some issues with this rather big update, and fixed most of those in greenDAO 3.1 (thanks to everyone who reported bugs!). The update also brings two new features:
Android ORM Performance 2016
With greenDAO 3 released, it’s time again to look at the Android ORM performance landscape and do some benchmarks. This time, we also tested newer ORMs for SQLite like DbFlow, requery, SQLDelight, and SquiDB. Also, we had an extensive look at benchmarks done by others. Let’s get started with our results:
Benchmarking on Android
I don’t believe in any statistics I didn’t fake myself (German saying)
Doing good performance benchmarks is hard and benchmarking on Android is no exception. Here is a checklist on how to do fair and robust benchmarks:
