Hello ~ I recently installed Tixati to do some torrenting. Everything seemed fine, but then I gradually noticed that my fiber internet throughout my house was running very slowly, almost 1/10th or at best 1/3 of the speed it should run. I searched all over for the problem and even called AT&T. Then I found by exiting and shutting down Tixati, I got my full 12mbs bandwidth back and the internet was running properly again. The problem was clearly Tixati.

I was aware of the bandwidth settings in Tixati and set them much higher than the default, but still way, way lower than my house bandwidth. But i noticed Tixati seems unable to take advantage of much of an increase in bandwidth. But even setting Tixati to a much lower bandwidth value did not help. Tixati seems to be eating up tons of bandwidth, therefore i have had to stop using it. Is there a way I can fix this problem?

thx

With drastically lower bandwidth limits 150KBs incoming and 40KBs outgoing, I seem to be getting better results, and speedtest performance is only slightly affected. I will keep experimenting.

It sounds like you simply need to stop seeding once you deem fit.

That's not very sporting, is it? Sorry, I don't understand seeding.

In practice, I have a 15 mb/s DL /2 mb/s UL service.

When I started running Tixati, it overloaded both my router and cable modem, causing a marked slowdown over time. My ISP is very supportive and switched my cable modem out to a newer, more robust model. I have not needed to reboot it since.

My previous LAN router couldn't handle torrent traffic well at all. after 8 hours or so I'd have to reboot it to regain normal bandwidth. US Robotics claimed abuse and suggested I get a CISCO router (for several thousand dollars!) I switched to another brand and it is much better, sometimes going for a week or two before I reboot it.

Lastly there is the program itself and yes, Tixati is still a work in development. with v 1.96 on WinXP32 I still experience the occasional CPU surge which lasts 30-60 seconds and causes all communications to halt and channels to disconnect. Even when not in this extreme state, channel connectivity is iffy.

I run tixati unthrottled as I seed 260 torrents. It does for sure use all available UL bandwidth which I hoped it would. Channels also use some bandwidth, especially when streaming but I am not seeing it "soak up" bandwidth needlessly.

I suspect you are really experiencing the opposite, that system overload is crippling bandwidth. As I indicated, there are many potential causes for this, yes, including Tixati in its current state but don't rule out other factors.

Thanks for the suggestions. So far, so good. I have toned down the speed to 150 incoming and 100 outgoing, and I am getting xlnt speed tests on speedtest   My outgoing graph is nice n flat but my incoming graph is a bit spiky. I am seeding 6 files but currently leeching only 1 file, so the 1 file seems more volatile in it's download bandwidth.

Unlimited upload will almost certainly slow down any connection. Try limiting upload to ~70% of it's maximum value with download set to max. You should get very good download speeds with this kind of setup. It's a good idea to have separate upload and download bandwidth presets with different limits. Tixati will change automatically between presets marked as Seeding and Downloading Defaults. Usually you should be able to upload faster when not downloading.

For example I have 40/4 mbps dl/ul (about 5000/500 kB/s), my presets are:
seeding: 200/400 kB/s
downloading: 3000/300 kB/s

I could set higher limits but I like to be able to use my connection for something else when Tixati is running :) . Also when you do a speed test you should close Tixati, otherwise the result will be false.

I've been using Tixati for a while now and I've noticed that the bandwidth limiting isn't very reliable as of yet to a point where it can easily exceed specified amount by at least 30 KiB/s. This might be what's causing issues here.

Well, I'm still having problems w version 1.96. Immediately after restart, Tixati is behaving itself, but tonight i ran a speedtest and it was 2mbs download -- should have been 11 or 12. Shut off Tixati, and speed goes back to normal immediately. It's really crazy. I have upload and download set to about 250-250, which apparently is too high. I'm backing off to 150-150. Seeding 6 files and downloading 1.

What's worse, Tixati is starting to play havoc with the computer's memory (I have 3 gigs installed, the maximum that windows xp can use). After a few hours of opening and closing a few applications, my computer's performance starts to get choppy and fragmented my mouse is stalling or even freezing up, which i haven't seen in many years -- certainly not on this particular machine. I have never had this with other programs such as photoshop, kmplayer, or googlearth. I want to get tixati off my main computer and onto a dedicated notebook computer, with tixati the only application running, so it doesn't interfere with my other programs. Then I'll try to find a good bandwidth setting that doesn't obstruct the whole network.

I have an AT&T fiber connection that runs at 12mbs so I don't understand why tixati should be causing all these problems in my network. That being said, it's a cool program.

You should find out what is your upload bandwidth. Usually it's much lower than download, for 12 Mbps connection it could be even 1 Mbps upload. Remember that speed tests often display results in bits and Tixati limits are in bytes, 1 byte = 8 bits. Your max download limit should be 1500 kB/s. Upload limit is more important, it can slow down your connection if set too high. For 1 Mbps it will be 125 kB/s max, but you should set it at about 70-80%, so 80 kB will be fine. Of course I assumed your upload speed is 1 Mbps, but it can be 1.5 or 2 Mbps, I don't know that.

Speed test results will always be lower than maximum advertised values when Tixati, or any other BitTorrent program, is running. This is normal, do a speed test when uploading some large file to your mail, you'll see lower speeds too. To find out what are maximum download and upload values, do a speed test with as low connection usage as possible.

Read this help guide: Optimizing Tixati.

If I have Tixati 1.96 running for a while, it causes my downloads to come in spurts and not smoothly. During the time there is no download, the Tixati UI is totally unresponsive.

Download speed depends on your upload setting and on the other seeders.
You could set upload really low like 1/10 of download while downloading. That worked best for me when I had such troubles.
You could also set your uploading to the number of peers lower like 2. For a slow group the best way to increase overall group speed is actually to seed as fast as possible. That way everyone gets the stuff rightaway and can seed the next pieces.

You can check how the other seeders transfer stuff to you by looking under the peers section.
Some seeders may not be able to or just don't upload at high speed. Look at the upload and download amounts from you and the specific seeders. Xunlei is a bad client that hardly uploads anything.
There could also be a performance problem with the reporting/analysis/event logs. I have set mine low to like 1 to 5 or even 10 minute intervals.

Dunno what else could be.

I think tixati is the problem. many times my computer just slow down so much and getting tixati not responding

I have the same problem but after I lower my outgoing bandwith limit it stops soaking up my entire internet connection (download speed increases simultaneously). Try lowering bit by bit and see the differences.
