Why MappedByteBuffer Beats FileChannel (And When It Doesn’t) – Deep Linux Kernel Insights

This article examines the internal read/write mechanisms of Java's FileChannel and MappedByteBuffer on Linux kernel 5.4, compares their performance through detailed source analysis and benchmarks, and explains why MappedByteBuffer often outperforms FileChannel for small I/O but can be overtaken for larger transfers due to page‑fault and dirty‑page handling.
