<DIV style="FONT: 10pt arial"><B>Subject:</B> [Opensim-dev] Kudos MW</DIV>
<DIV><BR></DIV>Greetings, List,<BR><BR>Just wanted to take the opportunity to
give the OpenSim dev team a robust pat on the back, an attaboy, a wtg peeps, a
standing ovation, and most importantly the heartfelt thanks and
admiration of myself and my colleagues on the OSGrid management team,
for the work reflected in the last 50 or so svn revisions; not to take
anything away from the 9900 or so prior revs *winks* but these last 50 or so
include some that have positively impact performance and stability in profound
ways.<BR><BR><BR><BR>Some that come immediately to mind as contributing to the
improvement:<BR><BR>r9951: MW <BR clear=all>Removed the List<NewForce>
m_forceList from ScenePresence, as there wasn't any need for a list, as only
the last entry in it was acted on. So it now has a single NewForce
m_nextVelocity , which is updated (rather than a<BR>NewForce object being
created every AgentUpdate). So as well as cutting out all the adds and
clearing of the list, it also removes the creation of upto 100+ new objects
per second per avatar.<BR><BR><BR>r9934: Dr Scofield for Allan
Webb<BR><BR>After noticing on several occasions that the thread counts<BR>we
see when running OpenSIm were bordering on the astronomical<BR>I decided to
seriously investigate.<BR><BR>After much poking I discovered that the problem
is actually very<BR>simple. The XEngine secition of the example ini says that
the<BR>timeout for an iden thread is in seconds, and an example value<BR>of 60
is specified. In fact, this is actually resulting in a 60mS<BR>idle timeout,
which is not normally enough for a smart thread<BR>to survive. I have added a
multiplier to the XEngine constructor<BR>so that the number now matches the
published behavior.<BR><BR><BR>r9925-9938: Dr Scofield<BR><BR>MUCH work to
streamline and optimize packet-handling code<BR><BR>r9924: Dr Scofield for
Alan Webb <BR><BR>Nice patch to streamline and optimize texture
processing<BR><BR>...and many more :)<BR><BR>We have seen available memory on
our linux plaza boxes go from ~380MB as of ~r9940 to a little over 1GB since
updating to r9952. <BR><BR>There's still a few problems - Lbsa Plaza was not
accepting logins this morning, but it was still running - and that after a
dozen hours straight of high-traffic uptime. This is a serious improvement, as
we have been seeing sim crashes there on a nearly hourly basis in recent
times.<BR><BR>Thanks Y'all :D<BR><BR>Keep up the good fight
:D<BR><BR>Cheers!<BR><BR>James<BR>aka Hiro_P/daTwitch/Hiro
