Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.

These powerful brands drive much excitement and, of course, dollars. The Apica LoadTest solution uses innovative technologies like monitoring nodes and load clusters to reliably deliver and sustain a large-scale load of virtual users (VUs) to Hollywood for different, realistic user scenarios all at the same time.

And today, we still have type in a digital context, but it travels through cables, wirelessly on smartphones, and in virtual reality glasses in 3D. Alternatively, if you want to do something new and expressive, or that has never been done before, then fine, of course. Stay tuned! Further Reading on Smashing Magazine.

HammerDB is a load testing and benchmarking application for relational databases. However, it is crucial that the benchmarking application does not have inherent bottlenecks that artificially limits the scalability of the database. Basic Benchmarking Concepts. To benchmark a database we introduce the concept of a Virtual User.

Of course, this requires a VM that provides rock-solid isolation, and in AWS Lambda, this is the Firecracker microVM. In this case, as the provisioning life cycle diagram shows, the worker node has to be provisioned with the given Lambda function, which does, of course, take some time. The virtual CPU is turned off.

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
