HeapPulse is a blog by Lobe Serge, an Oracle Certified Professional Java SE 17 Developer. I write about Java core and performance to help you understand how things work and how to make them faster without unnecessary complexity. I discuss topics like the JVM, memory and garbage collection, threads and concurrency, I/O and networking, collections, database access and connection pools, profiling and benchmarking. Your contributions, feedback, and support are welcome. Leave a comment, suggest a topic, or reach out on the contact page so I can make these guides more useful to you.
