Hi All,
We held our 3rd meeting on Tuesday 25th July. There's a writeup on Tim's blog about the meeting, and we have Sean's slides online
Here are the details for the next meeting:
| Topic | DTrace | |
| Date | Tue 25th July, 19:00 | |
| Location | Sun Offices, East Point Business Park | directions |
This month's main topic was DTrace. Sean McGrath, an engineer in the
Sun Ireland Performance Group gave us an introduction to the
Dynamic Tracing facility in OpenSolaris and will also be did some live
demos for us.
If you're doing any application development on any UNIX-like
operating system, and that app can be compiled on OpenSolaris, then you
really should investigate DTrace - it's well worth a few hours of your time
(and it'll almost certainly pay back that time a thousand-fold once you
learn how to use it!)
Sean's had asked that anyone who has applications which compile on
OpenSolaris (x86 if possible) that they bring them along, and we would have
a look at any possible performance problems they might have: DTrace is
best demoed on applications the audience is familiar with, so that was your
chance - if a bit of software has been bugging you, and you're not sure
what's wrong, DTrace can help. Examples could be:
- a webserver with unexplained (performance) problems
- you want to see what xmms is reall doing ?
- how a shell script executes
- why does my terminal-emulator take so long to scroll
(the list is endless)
We want your applications!
As well as that, did a quick run-down of OpenSolaris-related
things that have happened since our last meeting in June.
Regarding the location, if the East
Point venue suits everyone, then it's easy enough for us to reserve
rooms here, with projectors, internet connections, etc. but if people
think that's too inconvenient, other suggestions as to venues would be
welcome (esp. ones near pubs that stay open past 8pm (I'm looking at
you, East Point Bar!))
Thoughts and comments are welcome!
(oh, and tell your friends!)
