Lag Lag everywhere!

First in a three part series.

Recently I was given a link to an article about the dreaded Lag Monster all SL people have to endure. Gasp I hear you say – well to be honest some people just bang it down to the fact there are too many people on line and others to day that SL is having a ‘bad day’.

As models and fashionistas we are forever having to deal with the issue of lag not only in going about our daily lives in trying to race from store to store to buy that important outfit, hair, or set of killer shoes. But also deal with it during shows and events which require us to be at our best. Other areas of fashion are dealt a horrible blow when lag kicks in on their sim if they are designers and trying to upload things or make modifications to designs that won’t save. This is also most important for shop owners and running vendor scripts with delivery of items and for all where money is concerned.

The interesting thing this article discusses is some of the myths people have about Lag. For those of you that don’t have time to read the full article at http://analutetia.com/2009/06/22/anatomy-of-lag/ I will summarise it for you!

Basically one massive cause or even way that lag occurs isn’t just the draw on the servers created by lots of people in one particular area but in fact also your SL client application. It as Gwyneth Llewelyn so beautifully puts it ‘takes two to tango’. Each of these things has its own limitations and when they are pushed to the edge is when things start to go wrong. She goes on to say compared with times of old on SL where the servers and the clients found it hard to handle more then one aspect at a time even though a variety of things such as sending each avatar prim data and textures, tracking down on the sim where your avatar was and handling physics just to mention a few were needed to be done. In those days the only way to deal with lag was to make avatars as simple as possible. Shock – yes ladies that means sorting out that hair, getting rid of attachments and making sure the location was as simple as possible with cubes and blank textures. Could you imagine!

I took a picture for my personal blog of me attaching all my hair heavens know if i ever went for a SL walk about so to speak if I would be spiking the draw on the sims all over SL! See below.

Thank goodness now days things are much more different. Firstly on the side of the server things are being done in parallel and scripts will now only run when all else has been done. Hence why your AO, Hud or Chim might run a little slower at crowded events! Turning of AOs or entering ‘sleep mode’ on MystiTools or detaching everything with a script will really have no effect now to the lag of the sim all it will do is make scripted attachments run very very slow or not at all.

Gwyneth goes on to talk about the myths associated with lag and the etiquette that was associated in the old days with making Sims lag free. She does stress however that they made sense in the past but however don’t really apply to today. Turning off AO’s will not reduce lag – although many people still think they will. So she is suggesting if people still request this in politeness and SL etiquette it might be nice to do without the AO for a few hours even if it is only to make the requests by the host feel listened to.

What we as avatars need to do?
The cold hard facts are the following – the more prims a sim has on it the more textures our SL clients have to download which means it takes longer to rezz now days however the SL clients do have the ability to download what it basically needs and not to include every last little texture unseen. On the sim site basically the same happens it keeps a little list of what your avatar wants and needs based on the Draw distance you have on your SL client. The lower it is the smaller the interest list. Basically it means the lower you have it the less you are requesting and sending to and from the SL client and the sim.

Well now that I have totally made your brains hurt ! I will say that the next part concentrates on Sims and Shops for lag as well as looking at client lag which more realates to how you can help your lag. Lastly the third in the series will be lots of helpful hints on how to reduce your client lag.

May the power of lag be with you!
