This reduction in latency ensures that applications and websites provide a more rapid and responsive user experience. By analyzing disk I/O metrics, you can optimize queries to reduce disk reads or upgrade to faster storage solutions. Avoid over-indexing, which can bloat storage and slow writes.

From an engineering perspective this may be all that you need to know. The HammerDB TPROC-C workload by design intended as CPU and memory intensive workload derived from TPC-C – so that we get to benchmark at maximum CPU performance at a much smaller database footprint. This was both expensive and time consuming to configure.

On your first try, you can use it as a benchmark for optimizations later. An SSR application will generally have templating engines that inject the variables into an HTML when given to the client. Caching partially stores your data and is not used as permanent storage. Using the cache as permanent storage is an anti-pattern.

A Dedicated Log Volume (DLV) is a specialized storage volume designed to house database transaction logs separately from the volume containing the database tables. DLVs are particularly advantageous for databases with large allocated storage, high I/O per second (IOPS) requirements, or latency-sensitive workloads.

Accurate benchmarking rewards engineering investment that actually improves performance, but, unfortunately, inaccurate benchmarking is more common. If the benchmark reported 20k ops/sec, you should ask: why not 40k ops/sec?

Every little helps!
