From: Sidney Smalls AWM - Since you revealed your ignorance by stating that LL runs on OpenSim, maybe you should save us some of yout technical flatulence and post elsewhere. Go help noobs with questions about attaching their hair or something. From: Sidney Smalls And by the way, as the lead server engineer for another 3D world, I have to say that this reads like Star-Trek-speak. "We have to reconfigure the warp field transducers by rerouting the primary power coils and replacing the dilithium crystals." It is utterly meaningless.
LOL!

From: Sidney Smalls From: AWM Mars The biggest performance hit is always going to be the way in which the database structure is configured. Limited scaleability of the core system, combined with the pipeline networking nodes within the system. From: someone

Firstly, this Topic I started, based up a discussion about whether users see how they contribute to the lag or not. If you ARE a 'lead engineer for another 3d world' perhaps, you might like to elaborate on what elements constitute the Database elements of SL? Oh, and while you are about it... enlighten us all as to the name/type of platform software that SL is based upon? It is one thing to simply make a statement saying something isn't right, its another to explain what you perceive is right. The limited scaleability of the database structures used by LL is a known fact. As they are in the process of upgrading the pipeline networks that serve the database hardware, another known fact. Nodes are the controlling junctions for data distribution and connections. That should get you started.

That should get who started and why? you lose me AWM.. you want someone else to provide a solution to your problem but offer no recompense? Qoute: "It is one thing to simply make a statement saying something isn't right, its another to explain what you perceive is right." ok.. define your problem.. name your price.. then lets talk. http://www.contractoruk.com/news/004072.html10000 is not enough for me.

Lag affects everyone, its bigger than one person to state the obvious. Of course some have stated they don't give a dam about frames per second and texture loading speeds etc (the quality of the user experience), they are in a small minority like people who would still tolerate using a black and white television are. Of course I'm expecting people who care enough and are willing/paid enough to provide improvements to the user experience  .

LOL.. your funny... I don't suffer many of the issues/problems that a lot of people do, I do however help those that do, any way I can.. I don't consider it as 'I'm alright jack', nor do I search for some sort of recompense... I give where I can to the community. Sometimes that maybe simple awareness that lag and other issues are not soley from one source, there are many factors involved. I doubt you have anything to offer me, certainly nothing worth paying for. I built my own systems to use SL and VR platforms, I am luckier than a lot of people in that respect. If you have something useful to contribute, please do so, if not, hit the back button and move on.

Is all my fault. I have fabulous gorgeous super flowing hair made out ot zillions of prims and kool boots made with even more prims. Im a redline monstah !!! I sorry bout that but well Im just vain and shallow and selfish and ignorant and inconsiderate and I want a puppy I can carry round in my shoulderbag =p
So if you see me coming then best to just run away because I going to lag you to death, and if silly enough to want chat me about that, then I going to chat ur head off at a zillion miles an hour and u going to end up with a zillion lines of mostly nonsense on ur screen before u even get a chance to say bye and run screaming off down the road. Well sometimes anyways =)

Certainly AWM, your learning is probably well in advance of my own, and your knowledge succeds mine. It has not enabled you to solve the problem that brought you here, even the offer of $10000 by Linden i qouted, has not done it, for you, or anyone else yet. Yet. let me know when you have stopped laughing and solved the problem. Altruism? ok.. I`m watching.

Yet. let me know when you have stopped laughing and solved the problem. Altruism? ok.. I`m watching.  It was not a problem that brought me here. The sole reason I started this topic was to ask/poll people if they were aware, regarding the issues surrounding lag. I am particularily interested in a couple of fields, movie making, fashion shows and media equipment. All of which are subject to the effects of lag in the system. When combining movie making, with a fashion show, lag can play a huge part on the quality of the output media and the experience of the viewers both in and attending the show. When making movies, I am always monitoring performance of both my system and the sim/region that I am in, for the effects of lag. Whilst my system copes admirably with lag effects, I hear other people complaining they cannot move, rez objects/textures, clothing etc. When I check around, I see there are some that have very high Avatar Rendering Costs. Later I may chat with them and ask if they are aware of Avatar Rendering Cost. They complain about lag, but have no idea how or why they maybe contributing, they assume it's all to do with LL/SL. My comments in the openning post, considered how little control there is regarding lag contributors to the platform. Whilst land functions give Prim Limits, there are no limits to the amount of scripts that can be run, or how many textures are stored by every user, even inventory, it is in effect a runaway train. If LL are trying to gain stability in the platform, I have to ask why this remains unchecked? The nett effect is ever increasing issues for users. This is not meant to be targeted at any individual, or laying blame on users. It just seems logical that if a sim hosted on a server, has limitations of which it can cope with and remain stable within the network, then why are only prims the elelement that is capped? Why not scripts and textures to name but 2?

In all seriousness LLs code etc is probably outdated, in a mess and we'd all be better off if it wasn't.

From: Maylin Murakami In all seriousness LLs code etc is probably outdated, in a mess and we'd all be better off if it wasn't. What's REALLY outdated (or just plain stupid) is LL continuing to try to use MySQL to host the SL asset server cluster.. The SL asset server cluster is well into the multi-hundreds of terabyte region by now, and what works absolutely fantastic for small-to-medium databases, is woefully underpowered for the data warehouse that SL's asset server has become.. I joined SL in June 2005, and back then, I'd venture that MySQL was still ok for the asset server, but once LL opened the floodgates to all the freeby accounts, the asset database grew exponentially.. Now its in the size range that requires something a bit more suitable for this size of a database, ie: Oracle or DB2. Of course that would cost LL a LARGE sum of $$$, which they are loathe to spend... Being a system admin/DBA at work, I'm pretty familar with database issues, and I'm quite sure the problems are only gonna get worse as long as LL sticks to MySQL.. Pretty much everything (inventory/presence/teleporting) ties into the asset server, so there you go.... Tas

I'm having problems with SL as of yesterday. It has just been darn laggy and I can't seem to stay online for long periods of time. Not a great start, seeing I'm a "newbie" to SL.

First off, welcome aboard AngelJo.  And second, I do agree that SL has been lagging as of yesterday. I am always wondering what may be the culprit this time around. Or is it possibly because Christmas is fast approaching and more users are logging on lately?

I, too, have noticed a significant, sharp increase in lag over the past couple of days. I'm on a reasonably high-end laptop running Linux, and it normally copes very well with things that tend to make other people complain about lag. However, these last couple of days, I have seen some pretty severe lag, even in places where lag usually isn't an issue. I've even had lag spikes so severe at times that I've literally fallen through the ground on several occasions, or I'd be walking across a sim, getting about halfway, when suddenly I'm almost all the way back to where I started. So, I do agree that systemic lag has become a major issue all of a sudden.

@Katheryne Helendale Do you normally see 20+ FPS (without dropping below) with decent detail settings in a busy welcome area or venue?

In the foreseeable future would it be technically achievable to replicate the LL data centers at other locations on other continents to better serve those areas? Assuming money is no object and they use something better than MySQL  .

From: SuezanneC Baskerville I don't think LL uses OpenSim, i.e., SL is not based on OpenSim. It is in fact the other way round. The OpenSim project is based on SL's sim software.

Tas Agree completely, however migrating to Oracle 11g (My preferred DB of choice) would be a complete nightmare, as the SQL would have to be re-written to "oracleise" it. Once done, however the performance increase and reliability would be exponentially better.

From: Maylin Murakami @Katheryne Helendale Do you normally see 20+ FPS (without dropping below) with decent detail settings in a busy welcome area or venue? No. In those areas, I typically drop down to somewhere between 7 and 12 FPS. In quiet residential sims, I can exceed 30FPS (have gotten up to 41FPS a few times). I should note that I don't run fullscreen. The Linux client defaults to a 1000x700 window (at least for me), and that works well for me.
