I have an application which implements a state machine based on StateForge (StateBuilderCpp) generator. A state machine is defined as asynchronous and uses boost in the generated code:<br />
<br />

<pre><code id="code-10-29112197-1">&lt;settings asynchronous=&quot;true&quot; library=&quot;boost&quot;&gt;</code></pre>
<br />
Actions (implemented methods) are very fast but are called frequently - events are triggered with 10ms intervals. State machine uses boost ioservice.<br />
<br />
I run the application on a single core atom processor. Generally that pc is strongly utilized by others applications and I have noticed that sometimes when a cpu has a high iowait a dozen or so events are queued. Is it coincidence ? How to explains such behaviour ?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

multithreading

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.

System Programming

Programming theory deals with the design, implementation, analysis, characterization, and classification of programming languages and their individual features, along with introductory programming concepts like program structure, variable declaration and conditional and looping constructs. Sub-disciplines include the formal semantics of programming languages, type theory, program analysis and transformation, comparative programming language analysis, metaprogramming, domain-specific languages, compiler construction and run-time systems.
