The evaluation section has lots of good information on experiences running Delos in production, as well as some synthetic benchmarks. The in-production switch from a ZK Loglet to NativeLoglet was done for the first time on April 2nd 2019, and gave a 10x improvement at p99 for gets, and a 5x improvement for writes.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. top(1) showed that only the Cassandra database was consuming CPU. In 2019 myself and others tested kvm-clock and found it was only about 20% slower than tsc. What on Earth is Ubuntu doing that results in 30% higher CPU time!?

India has been the epicentre of smartphone growth in recent years, owing to the sheer size of its market and an accelerating shift away from feature phones which made up the majority of Indian mobile devices until as late as 2019.

On August 7, 2019, AMD finally unveiled their new 7nm EPYC 7002 Series of server processors, formerly code-named "Rome" at the AMD EPYC Horizon Event in San Francisco. Single-Socket Database Servers. The initial reviews and benchmarks for these processors have been very impressive: AMD EPYC 7002 Series Rome Delivers a Knockout.

Now, I am advising people to strongly consider AMD for SQL Server workloads as the AMD EPYC "Rome" processors are released in Q3 of 2019. This made it easier for database professionals to make the case for a hardware upgrade, and made the typical upgrade more worthwhile. So, what has changed my mind? The Death of Tick-Tock.

Similarly for this guide MySQL can be swapped for a mySQL based databases such as MariaDB. As is also the case this limitation is at the database level (especially the storage engine) rather than the hardware level. As is exactly the same with PostgreSQL for system choice a 2 socket system is optimal for MySQL OLTP performance.
