The speed of ScyllaDB stems from its shared-nothing, shard-per-core architecture, which maximizes CPU efficiency and concurrency. Built on the Seastar framework, it bypasses standard Linux kernel bottlenecks by performing direct I/O and managing its own memory and thread scheduling. By using C++ instead of Java, it avoids the performance hits associated with the JVM and garbage collection, allowing it to squeeze maximum performance out of modern NVMe storage and multi-core processors.
