First, I think the developers have created some awesome jailbreaks and 3rd party apps...I've used them since day one.

Second, Apple gets credit for 2.1 firmware which almost brings the iPhone 3G performance to the level of the original iPhone.

I’ve methodically installed and tested performance after each application to see the effect.

RESULTS:
1). Jailbreaking with QuickPwn or Pwnage Tool does not impact performance.
2). Performance hits come solely from 3rd party apps.

Of the apps I tested these have the largest impact on performance:

WinterBoard -
This apps is almost the sole reason I jailbreak, however, it has the most significant impact on system performance. After installing Winterboard, (without applying any themes):
- Increased lag in opening apps - 1-2 seconds
- Noticable keyboard lag
- Slow screen transitions
- Shutdown time goes from 5 seconds to 50 seconds
- Startup time goes from 20 seconds to over a minute

BigBoss Prefs -
One of my favorite apps “BigBoss Prefs” easily quadruples shutdown time. Unfortunately, uninstalling does not undo the damage.

I'm not a developer but it appears these apps are running background processes and/or impacting file system verification.

While i luv the app it literally negates all performance gains achieved with 2.1 firmware release.

Jay (saurik) are there options to avoid the performance impacts, even if it means turning off some enduser safeguards?

My battery life is very noticeably shorter after installing BossPrefs. Similiar to what your saying, the problem doesn't seem to go away after simply uninstalling it. Afrer restoring and never installing it again though I've had no battery life issues.

I have noticed that whether its Winterboard or Customize when I used it, skinning myiphone made all the menus just a bit slower.

I have noticed that Boss Prefs, one of my favorite apps, seemed to interfere with my signal in 2.0.2. I did install it on 2.1 so i could use the permissions fix so far so good on 2.1

Something is eating resources or making the OS work harder.
I think the old Services app would let you see and kill processes.

Does anyone know if there are daemons running with either Winterboard or Boss Prefs?

[Raven2k]

With yesterday's update to Winterboard a few performance bottlenecks were improved:
- Shutdown time has returned to 5 seconds or less.
- Startup time is around 30 seconds.
- Winterboard app is now extremely fast.
- Keyboard lag seems to be gone.

Opening apps continue to have increased lag time of 2-4 seconds (especially SMS).

Thanks to Jay for addressing most of the performance issues in Winterboard.
This was a great update.

I will also ask BigBoss if there is a way to enhance Boss Prefs or reverse it's performance impact. Well see, it may not be a priority for him.

Ill take the few seconds lag, I think its a small price to pay for making it look so much better.

Any program that could cause your iphone's lock screen to freeze up occasionally?

[nycdiplomat]

i dont know if this has anything to do with winterboard or anything else but sometimes the vibration strength lessens (not as strong) as it usually is, then i reboot and then everything is fine, then maybe a few days later the strength lessens. This happened before i upgraded to 2.1 from 2.0.1 so im thinking its a hardware issue. Has anyone else ran into this?

[Raven2k]

Chefanim, I agree, but this about full disclosure.

I noticed some developers note the performance impact their app will have:
example - AT Theme and recently Winterboard.

With so many apps this could have a cumulative effect.
But, it's more important to know if your going to take a substantial performance hit from a single application.

This becomes critical information to disclose when the impact is irreversible without doing a complete restore.

My battery life with 2.1 is significantly worse with the exact same apps/settings installed as I had in 2.0.2 with no problems at all. Viewing my usage stats, they almost always show usage and standby stats are identical, or, at least, usage is much much higher than it should be. With insomnia/ssh/top I've found that it's the mediaserverd process that is constantly running when it shouldn't be, using around 3% cpu time. I have no clue why this is. I've been trying to track it down, but I can't. It doesn't seem to be related to any particular app or anything. I also haven't found a reliable way to avoid it. I was thinking it's related to winterboard or bossprefs, but I have no idea. This week I think I'll try removing winterboard to see if it improves, but after reading here it seems that possibly it's bossprefs and irreversible (currently) which sucks. It also could be dock or quickgold I suppose too.

It also doesn't seem like everyone is affected, which is weird.

I notice the same problem since 2.1 came out for now I'm avoiding winterboard. Has anybody notice hang when opening 3rd party apps (Mostly when over 60)

Which problem do you notice... sluggish app opening or reduced battery life?

Pretty much all of my apps are a little sluggish to open, but I honestly don't think they are much worse than 2.0.2 was (jailbroken). I don't remember how fast they opened on 2.0.2 without the jailbreak/winterboard, and I didn't give 2.1 very long non-jailbroken/non-winterboard, so I don't have much basis for comparison, but the amount of time doesn't bother me too much anyway.

How is winterboard causing this sluggishness anyway? I thought it is basically just a front end for replacing system files with different ones? I didn't think anything was "running in the background" so to speak. I mean, what would happen if you uninstalled winterboard and just replaced the artwork files yourself, would there still be a performance hit?

[bhz1]

Sluggish apps all around but I do have much more reliable signal in 2.1 I only have. The thing is 2.1 worked great even with Winterboard and five icon dock until some Cydia updates last week.

Just rebooted my phone and it opened right to my springboard and not to the lock screen. Odd. It also will not connect to my wifi after full reboot unless I manually connect in settings. I have restored at least 4 or 5 times. So far the best results Ihave had was to use the latest Quickpwn for windows and install Open SSH from installer and not Cydia. Cydia will then notify that it has upgrades to Open SSL and 2 others (forget which) but when I installed them the problems reoccurred.

The most annoying problem is the fact that it seems that SSH/SSL will not stay functional consistently, I feel this is somehow related.

I also agree that the issues seem culmulative. After restore and jailbreak things seem great, yet after making various updates the functionality declines rapidly. Its as if the iPhone wants to remain un-jailbroken or at least unskinned, the very reason i still jailbreak my iphone. Along with not being able to connect on SSH, wifi wont work either even if it says I'm connected and all settings show in wifi settings.


Just discovered something regarding SSH. No mateer how many tries i could not connect to SSH this morning since rebooting my iPhone and PC and laptop. Well I plugged myiPhone into itunes and let it be recognized and low and behold, I was able to connect in Win SCP! i can also now connect on the other PC that I didnt even connect to iTunes on. WTF? iTunes is doing something to network connectivity?

I'm just a diagnostician, not a programmer, hope this helps some of you developers figure out whats up.

FWIW, my SSH has been working perfectly on 2.1. My wifi has also been OK as far as I can tell. There might have been one time that it was set to off when I don't remember telling it to go off, but I didn't think much of it as I think the same thing happened occasionally on 2.0.2.

I think my phone boots to springboard also, but I never pay any attention. It's not supposed to do this?

Is there any place that Jay posts to regularly about this sort of thing? A blog or something? His blog doesn't seem to get updates, but I'd sure love to hear about stuff like "hey, I know there's a problem with XXX that I'm working on to fix the sluggish app opening," or, "I think apple did XXX which is affecting battery life." He seems to have a great understanding of the phone, and I'd love to keep up with what he's working on. I don't have access to irc all day to keep up with it, but maybe that's the only place he uses?

[bhz1]

I just rebooted my iphone and ssh connected. I am wondering if it has something to do with a combination on updating certain programs in Cydia and rebooting the pc. My problems all started with an update of "mobile substrate" through Cydia. Although I'm not wondering if its permissions connected. But why when the connection issue occurs does plugging ointo itunes fix it even without a sync?

One more thing, it seems like when this problem starts, the iphone/itunes does not want to sync updates to app store apps.

Perhaps its a function of the itunes 8 recognizing jailbroken firmware?
