Fast and lightweight hash implementations (xdigest)

I was working on optimising Subversion. One of its bottleneck is computing file hashes. First thing I tried was to use OpenSSL for that. It significantly improved its performance. It made it 8x faster in some cases. However, it was not optimal to use it: - OpenSSL is heavy and bloated. It's like a whole operating system on its own. - Since OpenSSL 3.0, low-level digest APIs are deprecated, and instead they recommend to use EVP which might be slow in some cases. So I decided to create a new library for computing cryptographic digests. It basically takes OpenSSL's implementations, but with an…

    Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

  • Cachegrand – a fast OSS Key-Value store built for modern hardware2022 · github.com · ▲121

    I am the author of the platform, happy to reply to any question you might have! It scales up really nicely thanks to a year of research and development of the hashtable implemented in cachegrand, on the hardware used for benchmarking, an AMD EPYC 7502P, it was able to reach up to 5mln GET QPS and 4.5mln SET QPS, with batching up to 60mln GET QPS and up to 26MLN SET QPS. cachegrand is fast, it's fully Open Source, it's under a BSD 3-clause license - it can be used easily as standalone platform or incorporated in other ones without any licensing issue - and we are working to expand the Redis…

    Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
