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. Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? How would you _time_ time?

The architecture is: While the bpftrace binary is installed on all the target systems, the bpftrace tools (text files) live on a web server and are pushed out when needed. I see people think like a programmer instead and feel they must start by learning bcc and BPF programming in depth. That will be a quick and useful version 1.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. It was a great privilege. That's about 24 hours from now!

SVT-AV1 uses parallelization at several stages of the encoding process, which allows it to adapt to the number of available cores including newest servers with significant core count. It’s a nice building with good architecture! There exists at least one other alternative open-source AV1 encoder, rav1e.

These AMD EPYC processors have a number of advantages for SQL Server workloads, as I will explain in this article. This 14nm first-generation AMD EPYC 7551 processor has 32 cores and 64 threads, and it works in one or two-socket servers. This makes it a good choice for many SQL Server workloads, especially DW workloads.
