What codes make lag?

What are the most absolutley not able to move, make your hard drive gind, cannot teleport, slow you down laggy objects/codes in SL?

I was told that rotation codes were the worst. The ones you use for spinning signs? I see that when I go to a casino, it is very bad. What codes are making it so slow?

Most of that slow ya down to a crawl, grind your hard drive to dust kinda stuff isn't code, but textures.. Large moving ones are the worst.

Yeah and everyone thinks ships are bad.
Some attachments to avi's are far worse.

There Are some Sims as well, that have Natural Lag Pockets in them no matter what is on them. For example, there was a patch about 60 meters square in the North West Quadrant of the Old "The Wilderness" sim that Lagged Horribly even when there was Nothing placed within proximity to that area.

Probably a Hardware, or Firmware Bug.

Lag is a fact of SL just like Rain is a fact of RL (In most jurisdictions. Lol)

Angel.

Object updates are the worst ;0

up, up, down, down, left, right, left, right, B, A, start.

/me is so going to hell.

Nearly everyone you ask will tell you something different, because they each have their personal pet peeves to gripe about. However, what even IS lag is debateable, as you can clearly see in the support wiki on lag by LL itself.

In general (and putting it extremely simply), there are two major sorts of lag...server side lag that slows down everyone, and client side lag that only affects you.

The majority of client side lag (which is usually the majority of the lag people tend to call "lag" and complain about) is either connection lag or video rendering lag, or processing lag. If you video card, RAM, or processor isn't up to snuff, or your internet connection is subpar or has a lot of issues somewhere between you and LL servers, you get client side lag. Scripts and code do not tend to case client side lag as they run on the servers at LL. Oversized textures, excessive prim counts, and too many polygons in gneral (the building blocks of all 3D models) on the screen at once case video lag, while trying to process more than your chipset or RAM can handle cases system lag. Low FPS are cased by video lag 90% of the time.

Server side lag is different from clientside lag in that it affects everyone on that server the same. Excessive prims, big textures and lots of avatars do not tend to cause server lag as much as they cause video lag. The database does have to server up a lot of information if say you walk into a extremely busy club, so it is possible for excessive amounts of items to add to a servers load, but that is not the gneral cause of server lag unless you are trying to attend a huge event like the 3rd birthday event speech by Phillip. In an everyday situation, the maority of server lag in a given sim is gonna be caused by too many scripts running at once and doing too many things, thus taking up far too much of the servers own processing capacity. Note the sim server itself and the item database are seperate things. If it takes too long for that pair of new shoes to rez, then the item database is lagging from too many requests. If the entire sim is not responding correctly and your movement is lagging and the like, the sim itself is lagging from being overloaded. AOs, "listen" scripts in things like furniture, pose balls, AOs, collars, and security devices add a lot of script lag to a server...usually unnecisarrily as its listening even when you don't need it to. Scanners that update constantly and scripts that update vendors constantly also add excessive server side lag by making unneeded requests on the server's processing time even if no avatar is around. Things operated by voice commands use "listens" and thus the excessive use of typed voice command in SL does tend to be an issue...especially when twenty people show up in a shopping area with tonnes up auto updating vendors while all wearing listening AOs and attachments and carrying scanners and security devices.

Which type of lag is worse, client side or server side? Well, naturally everyone will tell you differently. Someone with a top notch system may never experience client side lag or low FPS, but yet bitch and moan about the server side lag when they have it in some sims, while someone who is plagued by constant video lag or processing lag due to underpar video card , lack of RAM or an older chipset will naturally think client side lag is worse. Just depends on your point of view and what you generally suffer from yourself.

As to your intended question...any code that is constantly running and constantly making requests of the server even when you aren't using it actively causes the worst lag.

That really clarified the lag concept for me. Complete succint
and well worded. Nice work.

The worst active scripting I've ever seen is some guy out in Rauche witha bunch of those tanks that appeared in star wars episode one (the droids piloted them). Each one was an autonomous bot with a health meter that attacked anyone but the owner. He was rezing them in rauche and they were shooting at everyone so I took him out, he came back, I killed him again, he then rez'd about 20 of them and it brought the entire sim down to a crawl. It got so bad that I couldn't TP out, if I turned my shield off and let myself die I would just reappear where I was. My phys disruptor wouldn't respond. Eventually to kill them all I set off a nuke right next to me as they all crowded around.

Mostly just alot of people in the area.

Clothes.

Clothes are the single most laggy thing about Second Life.

See, clothing is composed of what is called "textures", which are kind of like mosiacs composed of millions of tiny little squares. That's a lot of squares. Now, imagine what a typical person wears; Underwear, pants/skirt/blouse/shorts, shirt/top, socks or stockings. Perhaps even some kind of hat. All of these pieces of clothes are composed of these little squares, which are called pixels. Millions and billions and trillions of little squares coming through the internet per second. You can only imagine what that does to your internet connection!

Pixels cause lag. LOTS of lag. So, it's in our best interest to remove all of our clothing and exist in the virtual-world in our birthday suits.

Because remember, only you can prevent clothes-lag.

you fogot to tell them to remove their 1024 skins too

Spinning codes as you call them create almost no lag at all.
But like other mentioned, scripts that never go idle/lots of updates cause
sim "lag". Client side "lag" is caused by avatars and builds. So if you
avoid everyone and everything youll be lag free, lol.

Lag as people call it is hard to avoid in SL.
Basically just make a judgement call if the place
you are at is worth the "lag". -- If its not move
on to someplace else with more effiecent builds
and or less people.

And Fenrir's comments on clothing aren'nt quite correct.
There arent as many textures as there are pieces of clothing.
The textures get "baked" into a single texture.. Well 2 actually.
One for top and one for bottom. But the comment about
hi-resoloution skins/clothes is true. The texture size after
baking is the size of the largest texture for that part(top or bottom)

The price of beauty in SecondLife is...lag

Those are special low-lag pixels.

Especially the high detail skins.

Yeah.. Um.

Where was I? Yes! Clothes equates lag, so please remove them forthwith!

More beauty can be had for less lag. Less scripts, too.

Ooo, I got my low-lag-pixel-based super-high-rez skin on right now.. and nuthin else. It'll be lag-free in my sim! I'll TP ya when the grid's back up, K?

;P
