Monday with JVM logs
Introduction and safepoints logs
Heap after GC - do I have a memory leak?
My articles about JVM performance and tuning
Biased lock disabled, again
To tune or not to tune? G1GC vs humongous allocation
JVM internals basics - Stop-the-world phase (safepoints) - how it works?
Time to safepoint - finally there is a tool to find long ones, and yes it is the async-profiler
Can G1GC cause outage?
From one JDK bug to another?
How can inefficient algorithm degrade performance with innocent G1GC in the middle? Humongous object strikes back
Spring Boot + Spring Security + Apereo CAS + Concurrent Session Control = Heap memory leak
Spring Session JDBC + Apereo CAS = Heap memory leak, and it is a documented feature

My open source projects
I created some tools that help me with profiling big application with Async-profiler:
JVM/GC logs analyzer
Here is my open source JVM and GC logs analyzer:
