My last talk for 2017 was at AWS re:Invent, on "How Netflix Tunes EC2 Instances for Performance," an updated version of my [2014] talk. Our team looks after the BaseAMI, kernel tuning, OS performance tools and profilers, and self-service tools like Vector. Virtual Memory. We help where we can. schedtool –B PID.

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. CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. How long does it take to read the time?

Since its introduction by AWS in 2014, AWS Lambda has revolutionized the compute space and boosted the entire serverless movement. The virtual CPU is turned off. Stay tuned?for Dynatrace news. Dynatrace has offered a Lambda code module for Node.js After each execution, AWS Lambda puts the instance to sleep. functionality?in

SQL Performance

For SQL Server 2008R – 2014, you could lower this threshold using trace flag 2371. If you are on SQL Server 2008 – SQL Server 2014, for a single NUMA node with less than 8 logical processors, keep MAXDOP at or below the number of logical processors. That can take a long time on larger tables. SQL Server Agent Alerts.

I've suggested adding a command to docker to make listing at least the top-level PIDs in containers easier. ## Virtual Machines The two main technologies on Linux are Xen and KVM (and there's Bhyve for BSD). What happens if processes really do try to populate all that virtual memory?
