- ~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.
