in the dirty ecache has been limited. This patch was tested with real workloads using ClickHouse (Clickbench Q35) on a system with 2x240 vCPUs. The results showed a 2X in query per second (QPS) performance and a reduction in page faults to 29% of the previous rate. Additionally, microbenchmark testing involved 256 memory reallocations resizing from 4KB to 16KB in one arena, which demonstrated a 5X performance improvement.

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications.
