Sep 12Optimizing Performance of Simple Version Parsing in ScalaFor some time I wanted to write a blog post about performance optimizations: a step by step guide how to improve performance of some small portion of code. Something like I did in the past — Micro-optimization for UUID.fromString in 7 steps. …Java13 min readJava13 min read
Published inWix Engineering·Feb 5MySQL BLOB Fetch Performance in JavaWhat’s the best way to store binary data in MySQL? This is a question that has multiple answers, depending on what you want to achieve. For example, if you need to optimize for the storage size, you probably need to use some compression algorithm that compresses your data efficiently. …Performance8 min readPerformance8 min read
Jan 10Java Compression PerformanceData compression is a very broad topic, we may find lots of materials on this topic on Internet. There are amazing benchmarks for all kinds of compression algorithms. Benchmarks (1 2 3) for Java exist, but it seems to be a little bit outdated (not using JMH, for example) as…Java7 min readJava7 min read
Published inWix Engineering·Oct 27, 2022Java: Exploring JNI performance via Decoding Base64It’s time to consolidate my Base64 findings: take the best of JVM world, the best of Rust world and benchmark it together from within the JVM. In this article I’m going to benchmark Base64 encoding/decoding performance of java.util.Base64 versus base64 and base64-simd crates via JNI. …Java8 min readJava8 min read

Oct 16, 2022Base64 Encoding Performance: Java vs RustUPD: A lot of interesting comments on reddit: Added benchmarks for data-encoding crate. Added an optimized version of JDK ported implementation that brings Rust closer to JVM for encoding. WOW. Merged PR using base64-simd crate, which performance is almost 10x better than anything else! Blog post remains the same, if…Rust4 min readRust4 min read
Sep 24, 2022Base64 Encoding Performance: JDK vs Apache CommonsRecently I stumbled upon some old code that used Base64 from Apache Commons. So I decided to compare its performance to java.util.Base64. It’s not a new topic whatsoever (links at the end), so let’s just jump to benchmark results. Benchmarks Performance for encoding 10K characters for different JDKs. java.util.Base64 is a…Java2 min readJava2 min read
Sep 7, 2022Replacing HashMap with Off-Heap HashMap in Java?Wow, that’s the fifth (and I hope that last, famous last words) episode in my series “Benchmarking something that almost no one needs” :) I explored performance of java.util.HashMap vs scala.Map, and then tried to replace HashSet with sorted array and binary search, also storing this array off-heap. Then I…Java5 min readJava5 min read
Sep 5, 2022MySQL as Redis vs Redis?This is the next portion of my “research” around my UUID set cache. I’ve benchmarked Map Performance Java vs Scala, binary search instead of HashSet and even moving Set cache to Redis. Now it’s time to benchmark MySQL as such cache. This is a silly benchmark, I know. But just…Java4 min readJava4 min read
Sep 1, 2022Ultimate Off-Heap Hash Set: Using RedisAfter my post about making off-heap Set-like data structure, my friend threw an idea at me: why not to go all the way, and use not just off-heap, but off-process? Why not to try to use Redis as a side-car and have caches there? Indeed, why not to try? I…Redis5 min readRedis5 min read
