Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. When the word “performance” is heard, most people immediately think of speed. Memory utilization: The amount of memory required to process a request.

What about short-lived processes, like a service restarting in a loop? Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? top(1) showed that only the Cassandra database was consuming CPU.

Or let’s say that you’ve been getting numerous complaints regarding your onboarding/setup process for your product. When the work is ready to begin they go through an epic batching process to determine the more realistic scope of the work and what’s a feasible solution within the timeframe defined by the rough estimates. Pesky nails!

As datasets continue to grow in size, the amount of RAM required to store and process these datasets also increases. Benchmark before you decide. But also larger log files mean that the recovery process will be slower in case of a crash. If you see concurrency issues, you can tune this variable.

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”

Windows has long had a reputation for slow file operations and slow process creation. This weeks’ blog post covers a technique you can use to make all file operations on Windows run at one tenth their normal speed (or slower), in a way that will be untraceable for most users! Have you ever wanted to make these operations even slower?
