~4Dgifts/toolbox/perfTuning/XandSysPerf README
everything EXCEPT this README file hails from the
toolbox/src/swtools/XandSysPerf subtree and is
included here for completeness
files pertinent to X and system perfomance issues are collected here:
GoodXProtocolExample.text: X protocol usage summary for start up of xcalc,
as a good example of quantity of requests to start
up a reasonably well-behaved X client.
UsingXscope.text: describes how to optimize X Window System Clients
using xscope, an X protocol trace gatherer.
Xperformance.text: hit-list of X performance issues to be mindful of.
Xscope.text: outlines performance aspects of the X protocol,
using xscope for X protocol tracing, and the basics
of X protocol anaylsis.
OSmonTools.sc: minimalist showcase slides demonstrating the
benefit of timex, par (process activity reporter)
and padc (process activity data collector) as a
means of examining where the costs of process
execution lie on a system-wide level.
Note on PAR(1): use par to see system calls. One way to run it is:
par -si -SS <process name>
or
par -si -SS -P pid
The first one slows the task down but reports most
or all of the system calls. For the second one you
don't have to be root and it doesn't slow the process
down but it seems to drop a lot of system calls.
xprotostats: an xscope protocol trace groaker script.
