    I get 13ms for asset-cdn.agni.lindenlab.com and it seems to be in the Netherlands. What exactly do I ping and trace here?

     

     

    Quoted From Nalates blog;

    "You can check your PING time to your CDN servers using the command: ping asset-cdn.agni.lindenlab.com"

    http://blog.nalates.net/2014/09/27/second-life-news-2014-39-3/

    Was also tested at a TPV meeting by a few people when CDN was just on snack channel. Results will vary, it`s just coincidence that you get the same figure as me.

    CDN delivers textures/meshes differently now, not through the sim you`re on so ping sim isn`t as relevant.

    You can ping your local CDN cache by typing "ping asset-cdn.agni.lindenlab.com" in windows cmd.exe.

    I got 13ms last time I tried.

    CDN and http are all about texture/mesh download, how they`re then rendered is gonna vary depending on a users computer and viewer settings.

    You can see whats going on by using the texture console.

    CDN Problem or what? Objects not rezzing.

    There`s an even older trick to try and force missing objects to appear, Ctrl+Shift+r. The quirk of the missing objects has been around a long time before CDN.

    "I have found a interim fix to the “missing objects/have to right-click to see them” issue. Do a Ctrl-Shift-R to go to wireframe, then repeat toggling back to normal view. All the missing items are now there. Yes, a band-aid, but is better than having to right-click everywhere."

    I remember having to do that a lot, sometimes worked sometimes didn`t. Don`t see missing stuff half as often as I used to.

    Ummmmm......pretty sure this thread is about any improvements noticeable on latest sl viewer which is Second Life 3.7.19 (295700)  btw.

     

    Texture/ mesh fetch are pretty epic for me in W. Europe compared to what they were. Region crossings noticeably smoother in general but there`s always going to be ones that`ll dump you on the seabed or up in the air somewhere.

    I`d try leaving the texture memory slider at default on sl viewer Perrie an see how that goes for you.

    Scene loading is good at lower draw distance settings.

    TP`d to 3 busy clubs (50+ avatars each, 2 on magnum 1 on main) late evening UK yesterday, most avatars failed to texture (mine was ok). Texture console showed a log jam in FETCH with textues stalled in the HTW state.

    Possible tantrum from the UK CDN node coz of extra traffic now it`s gridwide?

    Early evening sailing/flying around Blake Sea regions was fine, region crossings were super smooth barely a judder.

    Logged in and out a few times with no problem.

    .......Is it my connection and how it reacts with the sl servers?......

    That`s very possible, theres been 2 reports of groups of users having their isp bug out on connecting with sl that I`ve seen on the forums in the last few months.

    I would try changing your DNS to google public first to see if that helps. Instructions here;

    If that doesn`t help then you could file a jira with a log from a session where you get logged out.

    Can Project Interesting is causing a bad scene render?

    in Second Life Viewer

    Take a look at SceneLoadRearMaxRadiusFraction in the debug settings in the advanced menu. To enable, go to Me>Preferences, Advanced tab, and check "Show Advanced Menu".

    By default it`s set to 75, experiment with lower numbers. I have it set to 1 for now.

    If you see a lot of grey, before you suspect your system, open the texture console (ctrl+shift+3).

    http://wiki.secondlife.com/wiki/Texture_Console

    Look at FETCH and CRE, a high number in CRE =  grey objects, a high number in Fetch = blurred textures. You can either wait for these numbers to tick down and the scene should render (could take a long time with weak gfx), or just drop draw distance to the minimum for a minute and then gradually raise it.

    Also cache hit rate has an effect on scene rendering low= slower, high = faster. You can check cache hit rate with the statistics bar ctrl+shift+1

     

    @ Perrie,

    I`d guess ther blur in the pics you posted is because bias is being applied. You can see bias in the texture console. Ideally it should be 0. For me bias rises when a lot of detailed textures are crammed into a scene at short range and results in blur.

    Lowering the texture memory slider will result in bias being applied more often. You can see it in action by having the texture console open and lowering the slider from 512 to 96. Bias shoots up and scene renders badly.

    Some sims/stores/avatars are so heavily textured that camming over them forces bias to be applied even on 512 setting.

     

     

    How do I launch the Linux Version?

    in Technical

    Posted

    Ignore install.sh, look for the "second life" file that has the same icon as install.sh. Double click that and select "run".

    Once you`ve run the sl viewer look in your desktop start menu, hover your mouse over "internet" and you should see a shortcut for second life. You can right click that and choose "add to desktop" for a desktop shortcut to make it even easier to start up.

    That`s how it works in mint 17, other distros may have different desktop features.

    Good luck and let us know how it goes :smileyhappy:

    "Ping Sim" in viewer statistics window

    in Second Life Viewer

    Posted

    If you look back at that link the text above the line

    "This service is live on Aditi now, in the “DRTSIM-258” channel "

    was edited when snack channel went live. The text below refers to the aditi test which was live for a week or 2 before snack channel was set up. The recommended settings are for the aditi test, not CDN in general.

    If you read that page but ignore all information about "agni" and "snack" it will read more or less how it did when the CDN test went live on aditi. There wasn`t a public version of http viewer at that time.

    The test was for any viewer and the 10,000 kbs advice was purely for the aditi test.

    A Linden stated at the last TPV viewer meeting (which is up on youtube) that once CDN is gridwide ping sim could become largely irrelevant, so might not be worth spending too much time to try and understand it. If you click help > about on your viewer menu while you`re in world you`ll see your current packet loss there.

    why the hair disappears after teleport.

    in Avatar

    It`s a common problem hair or boots disappearing from your av after teleport, some days are worse than others. Your hair hasn`t actually been taken off of your av it`s a viewer thing. Try zooming your camera out as far as you can and hit the Esc key to refresh the scene, that works a lot of the time, or just move your camera away from your av and back.

     

    Edited : " *** I can see it but others don't see***"

    If you use firestorm viewer I think that can be a lsl bridge problem. In your inventory look for #firestorm folder see how many bidges are in lsl bridge folder, there should only be one but sometimes there are many. Detatch all bridges then go to menu bar on viewer, click avatar >avatar health > recreate lsl bridge.

    If you`re using any other viewer I have no ideas, sorry, hope you find a fix:smileyhappy:

    I have seen the bad scene render you describe under those conditions both in latest firestorm windows viewer and sl windows viewer, it`s not connection related and clearing cache will make it worse not better. I`m thinking about whether to report in jira or query on the forums. I have dual boot system with windows 7.1 and linux mint 17, firestorm linux and sl linux render very nicely under the conditions you describe as does an old viewer based on Second Life 3.7.1 (30482).

    I`ll post a link to jira or forum query here when I get round to it.

    In the meantime if you have access to linux machine or feel comfortable trying it on your system go ahead and see the difference. You can try mint 17 on a usb stick without even installing it :matte-motes-nerdy:

     

    EDIT: coz I always forget stuff, that`s on these specs
