A MyRocks Use Case

Percona

The use case is the TPC-C benchmark but executed not on a high-end server but on a lower-spec virtual machine that is I/O limited like for example, with AWS EBS volumes. I decided to use a virtual machine with two CPU cores, four GB of memory, and storage limited to a maximum of 1000 IOPs of 16KB. . <iotune>

CheriABI: enforcing valid pointer provenance and minimizing pointer privilege in the POSIX C run-time environment

The Morning Paper

The basic question here is whether it is practical to support a large-scale C-language software stack with strong pointer-based protection… with only modest changes to existing C code-bases and with reasonable performance cost. code is not given access to excessive capabilities. We answer this question affirmatively. slower to 9.8%

What Adrian Did Next?—?Part 2?—?Sun Microsystems

Adrian Cockcroft

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.

Apart from library code, maybe your application doesn't have frame pointers either, in which case everything is broken. Only in extreme circumstances does the cost (in processor time and I-cache footprint) translate to a tangible benefit - circumstances which usually resort to hand-coded assembly anyway.

What programming languages does HammerDB use and why does it matter?

HammerDB

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.

A look behind the scenes of AWS Lambda and our new Lambda monitoring extension

Dynatrace

Dynatrace has offered a Lambda code module for Node.js Of course, this requires a VM that provides rock-solid isolation, and in AWS Lambda, this is the Firecracker microVM. The virtual CPU is turned off. This has led to the recent release of our new Lambda monitoring extension supporting Node.js, Java, and Python.
