Stock vs. Rooted+Lagfixed Captivate - Lag differences [Video]
Well, I haven't seen a side-by-side Stock vs Rooted+Lagfixed video so I put one together to show folks that the changes are drastic.
I rooted because of the horrible lag I ran into when using apps that save data while you use the app. Basically, anything that persists your selections as you make them. Games were mostly okay, since they only save when you quit. However, media players that save your position constantly, GroceryIQ which saves status every time you tap, etc.
This'll give you an idea of what I was seeing:
The non-rooted Captivate is my wife's... And after watching me make this video, she asked me to root hers as well. Then came a half-day of randomly hearing her exclaim things like "Holy CRAP this is faster!" and "Even swiping between homescreens is faster!"

Oh, one other thing I maybe should mention.
Do you play World of Warcraft? Do you have the Blizzard Authenticator on your phone? DO NOT ROOT!
Blizzard specifically checks for rooted phones and when you start the Authenticator, it gripes at you and shuts down.
So if you're going to root, either remove your authenticator before rooting or prepare to spend an hour on the phone getting to a live rep that will grill you before removing your authenticator.
UPDATE: As of the newest Battle.net Authenticator update (1.0.1), mine no longer force-closes.

I'm glad it works for you, but on both of the captivates I've rooted, the Blizzard Authenticator closes as soon as you select "Allow" or "Do not Allow" when it asks for super-user privileges.
It doesn't Force Close, it simply closes as if you'd hit the back button.
So, you start WoW on your PC and then fire up your phone to get your random-number-passcode.
My research tells me:
EXT2 can lose data if your phone is powered off (e.g. battery removed or dies) while the phone is writing to the internal memory. Not just at random times.
All of my important data (contact lists, email, etc) is stored on servers, not just on the phone. So, if it fails, I still have all my data available.
The link I posted now suggests that you follow a different method that uses EXT4 (which has journaling). It's the same method, but when it does the fix, it uses a "better" filesystem.
But, to be fair, Linux used EXT2 for a LONG time before journaling came onto the scene. EXT2 released in 1992, whereas EXT3 was introduced in 2001. So, it was "good enough" for linux installations for 9 yrs. I have enough faith that it'll run my phone safely for the forseeable future. (Until Froyo releases and this fix is no longer needed.)
But, like I said: do a bit of reading and make your own decision. No one's responsible for bricking except the person who does it.

FWIW, I was on a rooted stock firmware earlier. I flashed to JH2 last night, installed superrooter from xda and restored from ti backup. Now, the Auth did close the first time after giving it root access as you described, but I re-ran it and it worked fine after that, so who knows.
The feel of the phone after the fix is amazing though, this is how it should've been set up from the factory IMO. I've got quite a few apps that were amazing in every way except how slow they were, and now there's no problems at all I won't have to worry about data corruption since I used the ext4 fix, though it was a pain figuring out how to flash the firmware with no experience. I'm going to post up a small noob writeup of how I did it though in case anyone wants to do this.

It could go either way: they may have intended the app to still run and mine's mis-behaving, or they may have intended it to close and yours isn't listening. I don't think we can say what they really intended, but I'm glad yours is working for you!
Just for giggles, I removed/reinstalled the authenticator. It still closes after the superuser check.
I wonder if it has to do with the rooting method or Superuser app I used. My "Superuser Permissions" app icon is a ninja.

Cool, this video inspired me to install a lag fix. For those of you who are interested in a non-recovery mode way of doing it, there is an from the XDA forums that is super easy to use. It doesn't have the latest lag fix (not entirely sure what the differences are), but it boosted my quadrant score from 900 to 2100 Everything feels snappier as well.

I'd just like to see EXACTLY how somebody has successfully applied this method.
Did you make a nandroid backup before applying the new firmware and SRE?

+1 on the request for a newb-friendly step-by-step on this.
I see that an EXT2 fix is already on the Market, but I do see the appeal of using EXT4.
I haven't had a great reason to root my Captivate yet (and I hoped the Froyo upgrade would come sooner rather than later), but after seeing all the responses on the lagfix, I think it's time.

I just updated it a tad since SuperRooter got updated to include the overclocking kernel. And yes I made a nandroid backup via ROM manager before proceeding (this is also covered in my guide), thankfully I haven't needed it though.
For anyone not convinced this will help, the best example I've found is the 'Craigsnotifica' app. It's great, but before this fix lagged soooo bad. Now there's no lag *at all*; I'm amazed (and happy as a clam) at the difference

I rooted/lag-fixed my phone last night and the results make it well worth it. It's like a new phone. I sat and played with the phone for an hour without any frustration. The base mail app hits Exchange with no lag. Gmail works perfectly. The Facebook app, which always had the worst lag, works like a charm now.
To do this, there is a tool in the market called "One Click Lag Fix" that is easy, requires little technical knowledge and works like a charm. It's also easy to roll off the phone in case you want to (both the EXT2 fix and the Root can be rolled off with the app). I had problems with the 1.4 version but the 1.5 version did work. If you are not familiar with how to upgrade your phone/download zip files to the phone/don't have time to do all of this, you might want to get this app.
(if this should be in some other thread, please let me know and I'll move it).
Here are the steps:
1. Download the app and install via the Market or AppBrain.
2. Open the app
3. Choose "Root Device 2.1"
(the app will copy a file to the root of your SD card for you and will tell you that you need to reboot with the right key sequence).
4. Hold down the Up Volume + Down Volume + power button. The phone will reboot into "Recovery mode" - let go of those buttons as soon as you see "Recovery Mode."
5. (and this is where it's not too clear) choose to "reinstall packages." This will install the Root update on your phone.
6. The phone will reboot once it's done (if it doens't, reboot the phone yourself)
7. The phone should boot normally. Let it finish booting.
8. Re-open the "One Click Lag Fix" app again.
9. Choose "Install EXT2 tools" Let it complete.
10. Choose "OneClickLagFix v1 +" Be patient and let the fix install.
11. Your phone will reboot when it's done (if it doesn't prompt you to do it, do it yourself).
12. (IMPORTANT) the phone will show the AT&T boot screen and then will go black. Sounds will play but the screen will stay black. BE PATIENT. Don't think you bricked your phone - it's just taking a really long time to boot up completely (yes, like 1 to 2 minutes).
13. Once the phone boots up, enjoy the lag-free experience that is the Samsung Galaxy S Captivate with no slowdowns!
I hope this helps other people. I was intimidated by rooting but once I saw how simple it was and took the plunge, I was very happy with the results.
