other then just to "understand" mpstat, is there any particular reason you need to clearly understand this command? Are you a developer? Has someone come to you regarding multitasking of the OS? I guess looking for a bit more background here.

mutex or mutually exclusive (smtx) = kernel contention (if a thread can't acquire a lock, it spins).
context switch (csw) = "A context switch is the computing process of storing and restoring the state (context) of a CPU so that execution can be resumed from the same point at a later time." - wikipedia.org


I found some interesting articles from Princeton u.

You could honestly spend years understanding this stuff Smilie

NAME
Ns_AbsoluteUrl, Ns_ParseUrl, Ns_RelativeUrl, Ns_SkipUrl - URL manipulation routines SYNOPSIS
#include "ns.h" int Ns_AbsoluteUrl(Ns_DString *pds, char *url, char *baseurl) int Ns_ParseUrl(char *url, char **pprotocol, char **phost, char **pport, char **ppath, char **ptail) char * Ns_RelativeUrl(char *url, char *location) char * Ns_SkipUrl(Ns_Request *request, int n) _________________________________________________________________ DESCRIPTION
Ns_AbsoluteUrl(pds, url, baseurl) Construct an URL based on baseurl but with as many parts of the incomplete url as possible. Return NS_OK or NS_ERROR. Ns_ParseUrl(url, pprotocol, phost, pport, ppath, ptail) Parse a URL into its component parts. Pointers to the protocol, host, port, path, and "tail" (last path element) will be set by ref- erence in the passed-in pointers. The passed-in url will be modified. Ns_RelativeUrl(url, location) If the url passed in is for this server, then the initial part of the URL is stripped off. e.g., on a server whose location is http://www.foo.com, Ns_RelativeUrl of "http://www.foo.com/hello" will return "/hello". Returns a pointer to the beginning of the relative url in the passed-in url, or NULL if error. Will set errno on error. Ns_SkipUrl(request, n) Return a pointer n elements into the request's url.
