The Goal - A Process of Ongoing Improvement Plot Summary Alex Rogo is a harried plant manager working ever more desperately to try improve performance. His factory is rapidly heading for disaster part spends waiting for a resource, while the resource is preparing itself to work on the part ● Process time - the amount of time the part spends being modified into a new, more valuable form ● Queue bottlenecks. If we reduce batch sizes by half, we also reduce by half the time it will take to process a batch. That means we reduce queue and wait by half as well. Reduce those by half, and we reduce

bpfbox: Simple Precise Process Confinement with eBPF and KRSI William Findlay October 28, 2020 bpfbox at a Glance ▶ bpfbox is a novel process confinement mechanism for Linux using eBPF ▶ Users write Motivation ▶ Existing process confinement mechanisms are complex seccomp-bpf Unix DAC Namespaces Cgroups Capabilities Namespaces Unix DAC seccomp-bpf ▶ Existing process confinement mechanisms are prototyping ▶ Safe production deployment of new security solutions We have an opportunity to rethink process confinement from the ground up. 3 / 7 bpfbox Implementation ▶ Userspace daemon using the Python3

addition to the usual selection of modules which you can choose to compile, Apache 2.0 has moved the main part of request processing into Multi-Processing Modules (p. 59) (MPMs). Run-Time Configuration Changes Apache 1.3, you should select the PREFORK MPM. Other MPMs will have different directives to control process creation and request processing. • The proxy module (p. 504) has been revamped to bring it up to longer contains an independent src directory. In- stead, the sources are logically organized under the main distribution directory, and installations of the compiled server should be directed to a separate
