<div class=Section1>
<p class=MsoNormal>Test region: 40,000 prims (or there abouts), running trunk.
Testing a combination of factors including idle running, idle running with an
avatar, etc.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Random notes herein:<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>SceneGraph.Get* methods are generally very wasteful.
Lots of them use the /slow/ GetEntities method to build a list of entities
before searching them. This is particularly noticeable on the
GetGroupByPrim(UUID) method. EntityManager should be having indexes for these
frequently accessed items.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>SQLite processing one-at-a-time is very slow. Inserts
should be bulked for performance. I suggest running a ‘1500ms’ rule
on it.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Why, to send a primitive do we need to: - Mark it for
updates. – Crawl through the Entities list for updates – Send updates
to ClientViews, when we could just Send the update directly to viewers
(EventManager.TriggerOnPrimUpdated[?])?<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Why does Scene.Heartbeat/Update do more than just
updating frame-dependent things? Eg, why not keep Update to just: Update
Physics, Process Scripts[?], etc. Out of it we move: Backup (timer?), Land
update (when something happens+ timer?), Terrain backup (main backup thread?)<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-18.0pt;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Why build X copies of the same packet for fifteen separate
clients? Why not re-use the update packet and change the agent IDs? Maybe some
kind of ‘PacketMaster’ could be developed for each ClientView type
which allows us to do ‘bulk’ operations like this.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a feeling that with a few of these things fixed,
performance would increase dramatically.<o:p></o:p></p>
