Using ROMs: Performance increase?

I am considering using a custom ROM on the transformer, but is it worth it, I am mainly after performance increases. I see on a few that there are higher benchmark results, but does this actually translate into a real world speed increase?
I remember some custom ROMs for the original i9000 Galaxy S doubled the benchmark performance, but that was more down to "cheating" the benchmark than anything else, although it certainly was noticeable at times.
One of the slight criticisms I have of the TF101 is a slight amount of lag / lack of responsiveness occasionally - not a deal breaker, but if it can be improved then why not? Obviously not at the cost of stability though.
I think the SGS2 has spoiled me a bit here!

apparently there is a big increase (mostly from overclocking). i had the standard firmware for 3 days only, so I can't really tell, but one of my co-workers has a locked B70 and was wow-ed by my TF, the smoothness and speed of it.

Yes, I'm waiting too, to root it and put a cutom ROM on. I read, heard and saw the performance difference. Mainly from the overclock, but also thanks to kernel tweaks and stuff. So If you can root, do it

I've never been that keen on the idea of overclocking, as I prefer to have a bit of headroom, but I guess if it is safe and makes a big difference, then I would give it a shot. What would be a good middle ground for stability / speed ?

1.4 IMO is very stable and doesn't increase heat or use more battery but the real world performance is noticable. I have never run a benchmark so I can't give you any numbers. Just my normal use.

Cheers for the reply.
Is there any one ROM that stands out as being the best performing?

Contrary to what people think they all perform about the same. There is no source so everyone is building of the same stock rom. If you want the same look then go with Revolution. If you want a little tweaked then go with Prime (What I'm on). If you want the tweaks and a nice tools package then go with Revolver (What I was just running). All 3 devs are really responsive to problems
If you start from a clean base and don't restore any system data from other builds then they will all be fast. The real speed difference is in the kernel and those can be flashed seperately from the rom. Clemsyn is really putting out kernels this week. Some good. Some not so good. Go with whats right for you.
EDIT: I have actually installed all 3 roms in the last week and run them at stock and at 1.4 Ghz. They all performed exactly the same for me. They were all equally stable. I don't use benchmarks because they can be fudged.

I've used all three too. I notice huge improvements with webpage rendering. It's almost as fast as my laptop, where as before I avoided using the browser if possible. The ability to hide the status bar is a really nice addition to the latest version of revolver.
Edit: autorotate is also alot faster.

There is no such thing as an overclocking "middle ground" when dealing with mobile chipsets such as the Tegra. It's not like overclocking a desktop computer where the CPU will constantly run at the specified speed; mobile chipsets are pre-configured to utilize only as much power as necessary. For that reason I always ramp up my tablet to the max clock speed it can reliably handle, because then the governor will handle balancing between speed, stability, and battery life. My clock speed can range from 216Mhz to 1624Mhz, and on the interactive governor I can still achieve a good 8 hours of battery life from a single charge.
Of course that's not to say that you couldn't constantly run at 1624Mhz all the time, and I do sometimes lock it to that speed for games. But for much of the OS interaction, it's not necessary to run at full speed all the time, and you won't notice a difference even if it is locked at full speed. It just comes in handy every once in a while for things like loading apps, loading web pages, and playing games.

[Q] Looking for 2 ROMs that...

I am looking for a ROM that increases battery life, has beats audio, and looks pretty cool. I want to overclock my Sensation to 1.5GHz so making the battery life longer can balance out and i have regular battery life with a faster phone. It can look like Win7 but it doesn't have to. It would be cool to keep the Sense 3.0 but have having fewer processes so there is more room for multitask and gaming while keeping average battery life (maybe longer). Any suggestions?

Hmmm...Personally, with what your looking for, I would try out Coredroid. But I myself am using Android Revolution HD 3.6.7. I am having a bit of troubles with random reboots, and constant freezing up though. But that's just me. Just try em' both out and see which one you like

Is JB or ICS roms best for battery?

It seems jb is good for smooth and faster speeds, however it seems to give less battery life. Is this true? I was on jellywiz, and pa rom, seemed to drain faster. Is this just my OCD or is it true lol?
Thanks, let me know

[Q] Stock ROM much faster processor speeds than custom ROMs?

I'm struggling to get my head around this drastic difference in speed.
Stock ROM on linpack scores about 100Mflops on single thread, and 200Mflops on multi thread similar to this video at 2:50 http://www.youtube.com/watch?v=Zh5quKyypw8
However since flashing CM10 my linpack scores have more than halved! I never get over 80Mflops now on multi thread, and rarely over 40Mflops on single thread. Also in quadrant it shows my cpu scoring really low, but my RAM scoring very high. I was wondering if my the ROMs are effecting my processor speeds?
I am about to go back to the stock ROM to see if linpack scores shoot back up!

If you don't notice a difference who cares about benchmark scores?

Well I do agree with what you are saying, and it still seems very fast. But I used it for less than a day on the stock ROM, so I don't really have anything to compare it to.
I am wondering more if these benchmarks are giving false readings, or if they are actually picking up on some poor processor optimisations, which whilst may not be noticeable day to day, could have a greater impact on CPU hungry tasks such as making and restoring large backups etc.
But benchmarks for the sake of benchmarks I agree are pointless.

I pretty much stopped using custom roms that aren't based on official sense based roms because of low benchmark numbers, questionable battery life and terrible camera support.
HTC has most if not all drivers for the hardware closed source, so developers are trying their best but I just use the stock ROM

Your not getting false readings... That's just how it is.. Bench marks don't mean anything... Cm will always have a lower score than stock but is just as fast.. If your worried about scores flash a ROM based on sense ota...

amazing battery.. better possible?

I'm using current venomxl Rom with elemental kernel (all default other than max 1.5ghz and flu overclock off) and getting what I feel are amazing results on battery life. On phones of the past, aosp style roms pulled better battery life, but I saw here in the forums people were getting better battery life with sense roms? Is that true? I posted a screenshot below of my battery life, sorry couldn't figure out how to get jpg link from dropbox app.

Would be nice to hear what Rom/kernel combos others are using and what kind of battery life you are getting.

Put the picture in your public folder. Right click on the picture and click copy public link, or something to that effect then paste the link in your thread.
In any case, the only things you could do to get even better battery would be to undervolt your processor and maybe underclock as well. Some phones become unstable however and while I noticed the general ui and most apps run fine with a clock speed of about 1.2ghz, some, more CPU intensive apps do lag a bit. You can also disable radios when not in use. I actually use juice defender to do this for me automatically, which is pretty handy though not everyone likes the idea of having an app do that for you.
Last but not least, if your radio signal seems low most of the time, you can try flashing different radios to give you a better signal which will, in turn, increase your battery life.
Hope this helps, maybe others have had different experiences?
I use viper and bulletproof right now ad I wanted a stock kernel with swipetowake
And this holds up damn well in terms of battery life. Never used elemental for long though so not sure if it's better or worse.
*edit* I forgot to add, you can also turn off fastboot. Your phone will take longer to power on but saves some battery life.

Such reports are often just anecdotal and very subjective. Like you, I've also seen people claim better life on AOSP or certain ROMs on various devices, but never really experienced it in any consistent or meaningful way. Battery life often has more to do with the radio and reception in your specific care, than anything. Sure, various ROMs on various devices may have some subtle difference in battery life. But unless you are very methodical and scientific about comparing them, there are just too many variables involved, and you are often just left with subjective reports and placebo effects.
Can't open your pic. But if you are satisfied with the battery life (enough to call it "amazing"), I'd just go with the ROM that has the features you like the best, and leave well enough alone.
