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.”

If you are new to running Oracle, SQL Server, MySQL and PostgreSQL TPC-C workloads with HammerDB and have needed to investigate I/O performance the chances are that you have experienced waits on writing to the Redo, Transaction Log or WAL depending on the database you are testing. A good example of how tuning is an iterative process.

This means that there is no need to provision or manage servers (or even containers). These served as our benchmark when creating our Lambda monitoring extension. This means that, compared to running a regular web server, there are virtually no costs while users are not interacting with your site. Auto scaling.

In this post I'll look at the Linux kernel page table isolation (KPTI) patches that workaround Meltdown: what overheads to expect, and ways to tune them. I then analyzed performance during the benchmark ([active benchmarking]), and used other benchmarks to confirm findings. Much of my testing was on Linux 4.14.11

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. This server is spending about a third of its CPU cycles just checking the time! Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object). A quick check of basic performance statistics showed over 30% higher CPU consumption.

The virtual CPU is turned off. When we set out to create the new Lambda extension, we benchmarked other dedicated Lambda monitoring solutions that were already on the market. Stay tuned?for If there’s an idle instance of a Lambda function available, no cold start is needed, and the function can be executed right away.

For anyone benchmarking MySQL with HammerDB it is important to understand the differences from sysbench workloads as HammerDB is targeted at a testing a different usage model from sysbench. Download and install HammerDB on a test client system, Like PostgreSQL another 2 socket server is ideal. HammerDB difference from Sysbench.
