The recently revealed [Meltdown and Spectre] bugs are not just extraordinary issues of security, but also performance. The patches that workaround Meltdown introduce the largest kernel performance regressions I've ever seen. Some older kernels have the KAISER patches for Meltdown, and so far the performance overheads look similar.

We’re talking about a few hundred milliseconds, but this can have a considerable performance impact when cold starts occur too often. The virtual CPU is turned off. The result is overall performance metrics that provide valuable insights into how a function is performing regardless of the instance that handles the request.

The spread of where consumers want to consume content, at home, at the office, at the gym, on a plane, at any time where there is connectivity, puts significant pressure on the network and performance monitoring teams for streaming brands. Consumers will leave you for slow or intermittent performance because there are other content options.

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.

I use the “built in” benchmark pgbench to run a simple set of queries. Since I am interested in only the gains from hugepages I chose to use the “-S” parameter to pgbench which means perform only the “select” statements. The goal was to see what gains can be made from using hugepages.

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here. A quick check of basic performance statistics showed over 30% higher CPU consumption. How would you _time_ time?

This post complements the previous best practice guides this time with the focus on MySQL and MariaDB and achieving top levels of performance with the HammerDB MySQL TPC-C test. As is exactly the same with PostgreSQL for system choice a 2 socket system is optimal for MySQL OLTP performance. HammerDB difference from Sysbench.

Though still not “profitable” by many benchmarks, it’s a lot closer to being so, perhaps in a big way.) So if they can’t beat ‘em in the DBaaS space, they often feel like they have to join ‘em — to the tune of total stack sharing or some proprietary arrangement. ” Nothing nefarious there.

This will help you increase system performance and avoid I/O environment errors. Atomicity A transaction must be an atomic unit of work; either all of its data modifications are performed or none of them are performed. For specific information on I/O tuning and balancing, you will find more details in the following document.
