Hi there TL.



I'm coming here about 1 hour before our beloved NASL scheduled transmission to try to solve a problem that a decent amount of people seem to have. I didn't have it before with JTV, but since doing a little research it seems it can happen with pretty much any JTV stream.



EDIT: I will say it here to be clear, this issue has NOTHING to do with Hardware Specs, ISP, download throughput or, sometimes, even software. And they can be kinda random, I can't watch TSL because ustream lags too much, even on low quality, but I couldn't find a solution to that yet. But Justin.TV works fine and I'm trying to help people where I can.





The reason it LAGs, for many people (including me yesterday) was because the CHAT gets so full and has so many people messaging it can use a LOT of computer resources...



This coupled with the huge bitrate that the NASL videos are streamed in can put some modern PC's to full load. Or rather 1 core of a modern PC to full load.



The issue here seems to be that flash and most modern browsers are not particularly multi-core friendly, and thus a lot of computer resources go to waste.



Most people have problems when they watch like this:







I use Catz stream as the example because it is available right now.



EDIT: This is a screenshot of the state of my PC when I open the Fullscreen 480p NASL stream with the chat open behind it, no core realocation done. And yes, it LAGS like all hell.







To solve this we have some options:



Solution Number 1



- Don't open the chat at all.



It can be done by watching the stream from Team Liquid (see right hand bar), or directly here



If you open through Justin.TV you will get the chat going.



Another, and the most obvious solution was pointed quickly by Mairu. I don't know how the most obvious things are left behind!



EDIT: I don't know if this stops downloading and processing chat or just hides it, bewaqrfe until furtgher tests

VIOLA! No chat. VIOLA! No chat.



Solution Number 2



- Pop-up the stream



There is a button on the right-bottom side of the stream that does this. Doing this CAN automatically solve your problems (As the browser/Windows get smart and actually use 2+ Cores) or you may want to close the chat window behind it.



If you want to keep the chat window and this does not work for you, there is solution number 3.



Solution Number 3



- Change Core affinity in windows



This can be done both in windows XP and 7, and Linux/MAC too, I'm mostly sure, but I don't know how to answer to those two operation systems.



First do something every Windows user should know how to do Ctrl+Alt+Del. It will open the Task Manager. Alternatively right click the Task Bar in an empty spot and click Task Manager.



After that go to the Process bar, like this:







See that even though I'm watching it in 480p (and MUCH lower bitrate than NASL) and the chat is only mild it is eating 16% of a 3,2GHz Phenon II X3 processor.... Since this is only on 1 core it is actually 50% of that core.... See how can this can add up pretty quickly?



Well, next step should be right click that bad boy of a process and select "Core Affinity", it will open a small windows like this:







Uncheck lower number cores, because those are automatically assigned first. Leave it with the last or last couple of cores.



If you have multiple High Load process, you can separate then to different cores as well. Since in this case only 1 process is eating my Cores, I shoo it to the last core and I'm done with it.





This, I think, can solve 50%+ of the lag problems people got with the NASL stream yesterday.



If something here doesn't work for you, please leave a message in the thread and, if I can, I will help. I don't have anything to do with both NASL nor J.TV, I'm just trying to help people, since I had this problem yesterday and think more people need to know about this.

Try reading this article (has a link to a program you can use)

no.



i always use tl links to streams, i never open chat. other popular streaming services are fine for me (own3d, ustream). justintv is lagging, not my pc because of lack of recources (12mb/s dl, i7-2600, 16Gb ram, ... lack of resources ?).



explaining the issue.

Worth a try solution if nothing else works:

You can also disable hardware acceleration in the flash menu and/or increase cache to improve performance. Just right click on the stream and go to settings to change those things.

Not sure if this helps, or if ti was a coincidence, but hopefully this might be helpfull to someone.



I was having bad lag issues with both the 1080p stream and the VODs. I haven't gotten to check stream yet (I'll try to check tomorow during the restream so I don't have to wiat til lwednesday to know) but I was trying to fix the lag with the VODs just now. I tried the things listed in the OP and they didn't really seem to work. But I then found above the core affinity, "set priority" And by changing priority from normal to high the lag suddenly went away. Not sure if this is helpfull at all, and like I said I will test this tomorow with the restream and get back on weather or not that fixed the stream as well. But it fixed the VOD lag, while nothing else seems to have before for me.

Anyone who still has problems:



Please, post your PC specs, software versions, browsers, flash plugin and anything else you can think of. I am thinking it may have something to do with specific ROUTERS or router configs, so post router make and model (be it Ethernet router, wifi router or modem-combo-thingy)



EDIT:



VERY IMPORTANT FOR ANYONE WITH PERSISTING PROBLEMS



Anyone who still has problems post a screen of you watching it FULL SCREEN with the following options open. Open Task Manager (explained earlier in the post) open the Performance tab and then the Resource Monitor, put it on the Network tab and put the Task Manager in the process tab. Like the screen below:



(There's no problem if Task + Resource Manager are on top of stream if you don't have dual-monitors.
