iPhone Nitrous

[RolandNights]

So far I've noticed Flipboard is MUCH snappier after installing Nitrous. AlienBlue and Reeder have also been quicker for me.

I'm going to test Hulu+ and Netflix while I'm on the treadmill at the gym in a bit. I hope it improves the buffering even though the reception at my gym is mediocre.

Anyone else recommend this TCP Optimizer?

I do. It's helped me a lot.

 

[bushbabywas]

which apps?

what's the easiest way to tell which apps use javascript? so we know which ones to enable Nitrous for. Apart from Chrome and Facebook, those with in-app browsers like Reeder, Instapaper, Tweetbot. Gmail as well presumably?

 

[noiceT]

Nitrous Updated. Fixed the crashing problem

 

[BumpyFlatline]

I know I already posted my recommendation for both Nitrous and TCP Optimizer but I do want to say that I have read reports that for some users, TCP Optimizer either slowed down their internet speed or worse, prevented YouTube from working at all. A simple uninstall of TCP Optimizer fixed this problem. I had to power down then power up my phone for the tweak to work. Just pointing that out.

I can firmly say though that both tweaks combined have greatly sped up my Internet connection and improved my overall experience a ton. In fact, my co-workers and I compared phones today on our works' wi-fi network. It was my 4S vs a stock 4S vs a HTC Thunderbolt vs Samsung Galaxy S2. And my jailbroken 4S with these two tweaks installed consistently loaded YouTube videos (via ProTube), embedded YouTube videos, and random websites faster than each of their phones. Sometimes one of their phones loaded a page first. But more times than not mine finished first. Needless to say, my coworkers' stock 4S will be jailbroken tonight haha.

Just installed it a few minutes ago.

Nitrous+Browser Chooser pretty much makes Safari useless on the iPhone.

Totally love this tweak. Well worth the .99.

How much difference does this make on normal sites like this one? Dont even see it on cydia anymore.

What do you mean by normal site?

It's there.

I'm using Nitrous and TCP Optimizer.

It's there.

Found it. To be honest Chrome actually seems slower at loading pages?

Where can we locate TCP Optimizer?

From Redmond Pie:

In order to install this tweak, you need to add the http://cydia.pushfix.info/ repository to Cydia, or any other compatible package manager. After refreshing your sources, you should see “TCP Optimizer” on the package listings. The tweak should take effect right away, without a restart, and enable you to watch YouTube videos at decent speeds.

I don't. My connection became laggy after this was installed. I think it really depends on you -- the author himself states that it worked for HIM so he's not giving any guarantees.

Still, it's a worthwhile tweak for those whom it works for. Plus, it's free so you can't beat the price.

 

[otosan]

I do recommend this both tweaks,

after update, Nitrous is no longer causing safe mode, and the performance gain is good, especially in chrome.. and bleacher report team stream in my case...

facebook is sucks from beginning so i can't say much and not even bother to really compare the performance before n after

Have you done a speedtest to see if this tweak made any difference? I installed it and my speed was stupid slow

I used the Ookla app SpeedTest from the App Store and the speeds were about the same for download and upload, with ping being noticeably better with TCP Optimizer. Websites and videos definitely load faster with the tweak than without it. Keep in mind it's not going to dramatically increase your download and upload speeds. If it added several MBs to the overall wi-fi speed, Apple would have designed the phone to do this from the get go. It's effects are similar to how Notrous works. Real world use it's negliable but in my opinion any added benefit I can get without hampering my experience, then I'm cool with that.

I'm not sure why you had slower speeds though. I have read reports from people saying their speeds got slower because of this tweak.

Finally after the update took the plunge and definitely the results are good when it comes to benchmarks.. As you can see in the snaps the effects are obvious. But don't see much of a difference in real scenario usage.. Have attached photos showing sunspider results.. Also the browsermark results..

I didn't know about that first site rightware. Pretty cool. I just ran the test and scored 76463. But like you said, you don't see too much difference in real world usage.

Are you on a 4 or 4S? Because on my 4S Google Chrome is just a fast as Safari now. I'll post screenshots of my results later on today when I get home from work.

 

[ACardAttack]

Alien blue is a lot better with this fix,and I'm starting to notice face book being better too...I'd buy it just for chome! The others are just the icing on top

 

[labman]

well I just bit the bullet for .99 no crashing 5.1.1 4S so far any way. I'm not going to say much about the speed yet till I play more.

 

[noiceT]

I think the differences are more noticeable on a 4s rather than a 4. On my 4, safari still feels snappier (even though the benchmarks show chrome slightly edging out safari).

One interesting note, Tweetbot is noticeably faster–especially when viewing photos.

Nitrous and TCP Optimizer are not for increasing your download or upload speed, it optimize how your device utilize the speed they got,

testing it using speedtest won't show you significant improvement as the maximum speed of the internet itself is not change

This is my understanding as well. With TCP Optimizer, it allows for more "out of order" or "missing" packets to be received by the iPhone. Normally what happens, since wi-fi is more unreliable than wired, the phone allows YouTube to continually send packets even though some might get lost along the way. The phone re-requests any lost packets so it can continue streaming the video. But the phone can only "buffer" so many extra packets at one time because it's still receiving all the other packets that are coming in order from the server. This tweak theoretically increases that buffer limit. Since the phone recognizes packets are getting lost it needs to stop accepting new packets while it asks the server again for the already missing packets. Therefore with this tweak installed, it increases the threshold for the number of unaccounted for packets which basically allows YouTube (or other websites) to continue sending packets while the "backlog" of missing packets grows. The phone will sort out the confusion on the fly by asking the server to keep sending new packets while simultaneously asking the server to resend the missing packets. The phone keeps receiving all of these packets and it processes and organizes everything as fast as it can which, in the case of youtube, results in a video! This in a nutshell is how the TCP Protocol works. UDP is the opposite. UDP allows a server to send packets in bunches and they may or may not ever reach the client.

This is why Otosan said it will not increase your download and upload speeds. The results from a speed test reflects the completed transactions of packets. It does not account for the "buffer" of missing packets. This is why it won't show up on a speed test but you'll notice YouTube videos load much better. The phone will continue asking the server to resend packets while the video plays. All of this is unnecessary on a fast network with little traffic but is somewhat helpful on a slow, congested network because of the high probability of packet loss. Toe this is all theoretical and assumed. I am not aware of any real world test that could quantify this tweaks performance. Many people have claimed this tweak slowed down their phone. I'm gonna play around with it for some time and see if I can determine definitely that it helps or hurts my iphone's wi-fi performance.

I hope this helps clarify the tcp optimizer tweak. And if I'm wrong with anything please point it out. I'm still learning and love knowing when I'm wrong. It's easier for me to remember stuff when people point out my errors! But this is how it was explained to me.
