Please note. All benchmarks were ran on BB 0.4 with the most memory I could keep available for the tests.

I mainly did this because of the threads that were popping up on which kernel to use. Granted each phone might be different but these are my results.

Just some benchmark results. Not much of a difference.

Quadrant Score. Each benchmark was ran 2 times.

1513 - Chevy ULV 1.2ghz
1563 - P3 LV 1.2ghz
1546 - P3 Normal Volt 1.25ghz

MFLOPS Scores. Each benchmark ran 2 Time. Thus far the first benchmark run was also the best results pf the two.. Surprisingly both P3 kernel ran the same.

17.406 - Chevy ULV 1.2ghz
16.812 - P3 LV 1.2ghz
16.812 - P3 Normal Volt 1.25ghz

So from my conclusion the best Kernel to run out of the three is P3 LV 1.2Ghz. No reason to run P3 1.25, same scores, however some may benchmark a little higher then others but i assure you it wont be by much and it WILL drain battery life a little faster.

Hopefully this helps some people out. If anyone wants me to some more Kernel testing post up.

The only issues is your conclusion is based on faulty results. As part of my research on Overclocking the Droid, I have found one thing to be an absolute fact. When using Linkpack to test a kernel, you must remove EVERY application possible and boot the phone with only the OS being the choke point if you are going to only run the test once or twice. Otherwise you must run the Linpack benchmark 10 to 20 times and look for the best MFLOPS. The reason for this is simple. Linkpack is a straight CPU benchmark. That means it can only test the clock rate of the CPU and nothing else. And since ALL kernels have to obey the same laws for running on the OMAP3430, the results will ALWAYS be the same if you remove your background apps and streamline the OS to the bare minimum needed to boot the phone. So a P3Droid, Chevy, Bekit, etc kernel that is clocked at 1.2Ghz will ALWAYS give the same result in linkpack if you setup the test properly.

And if you wish to test this theory, feel free to use the following formula under any Froyo 2.2 ROM and kernel combination with your standard load out of apps. Set Advanced under SetCPU to 32000, 20, 0, 0. Turn off all profiles. Set Min and Max to top frequency choice. Run the benchmark 20 times quickly, remember the top MFLOPS and then take MFLOPs / .01606 = CPU Frequency.

Your current results come out to:

17.406 - 1083.81 Mhz
16.812 - 1046.82 Mhz
16.812
- 1046.82 Mhz

That means your test results have a 10% error right now. Which is usually considered a large enough discrepancy to invalidate them as useful for making an informed choice.

No one at present has developed a benchmark that is truly useful to pick the best kernel for a particular Droid with a particular load out of apps. I have spent the past four months trying to figure out a way to do just that. And every time I find the flaw in the testing.

BTW, Quadrant has the same issue as Linkpack. The very fact that you can get different results based on running it 10 times, should prove that beyond question.

This is my best Quadrant benchmark yet.

Originial Droid, running BB, P3 1000Mhz kernel (250 minimum), and Blue Energy theme.

These posts just go to show you how much results vary on different Droids. I've tried every single Froyo kernel available, at least at 1.0Ghz and above. None of the jdflg kernels will even boot on my phone (but some folks swear by them); wait, I take that back: one of them (I don't remember which speed) did boot all the way up, but showed 0 battery when it did, and I was at plugged in and at 100% at the time. The P3 kernels all either won't boot or reboot constantly once they boot up. The jake kernels wouldn't boot for me, and so far Bekit only has an 800Mhz test kernel out. None of the Chevy ULV kernels would boot, and only the Chevy 1.0 and 1.1 LVs would. I used to be able to run Chevy's 1.2Ghz MV kernel on pre-Froyo ROMs, but the 1.2Ghz MV Froyo kernel reboots randomly.

All of my kernel testing has shown that, for my Droid on Froyo, the ONLY one that boots up consistently, and continues to be stable without any heat issues, is Chevy's 1.1Ghz LV kernel. With that 1.1Ghz LV kernel, I'm getting Quadrant scores between 1500 and 1600 consistenly, and that's running BB v0.4 with a modified NexTheme and my normal heavy load of Sweeter Home 2 with 20 widgets and 107 non-system apps. It is snappy, smooth, and has no lag on my setup.

Everyone's Droid is different, and kernels perform differently on every Droid and sometimes even between ROMs on the same Droid.

The only way to judge a kernel's performance is by testing it yourself on your own Droid.

I tried P3 Kernels and I loved them on 2.1 (and the respective BB versions), but on BBv0.4, they seem to run hotter than Chevy. Although, Chevy's isn't fun either. I had 1.2 Ghz kernel and when I tried to use the navigation on my Droid, it locked up and rebooted, which I'm assuming is the direct result of overheating. 1.1 GHz has been the most stable for me, and I can get some pretty low temperatures.

If you install a kernel and your phone runs hot, why use it? I can see it running warm when you first install it or that it may run warm for the first few mins after a reboot as the os is loading, but if your phone stays running hot you really ought to consider another kernel. While processors are designed to get hot, there is a point of failure. Also, running hot like that is also going to effect overall life of the CPU. Your also not going to get decent battery life running under those conditions.

This is the kernel I ran to get the 1726 on Quadrant, 250-1250-v32kernel from P3. It was ran on a Moto-Droid, with this release from Pete...VIRGINDEODEXEDFRF84B.zip

I'm only getting 1196 using Chevy's uLV @ 1.25Ghz and Simply Stunning v4.5. Before I was getting 1022 using his LV@1.0 GHz and SS v4.4.

I just don't know why my scores are so slow compared to everyone else's here. Any guidance?

I just got 1426 in quadrant. Motor Droid running Chevy's 1.25 ulv kernal. Not sure how good that is, but my phone doesn't really ever get hot with regular browsing. Battery life is also solid

I ran Quadrant earlier today and got a 1550, running a full load (heavy Sweeter Home 2 theme, 107 non-system apps, 20 widgets, Swype, etc.), with Chevy's 1.1Ghz LV kernel.

I just tried two p3 kernals, got quadrant scores below nexus 2.2 both times. Personally am getting the best results with chevy at 1443. How come I can't get 1500+? Running on demand 1.25 ulv chevy, have a droid..

How many widgets do you have running?

0, I tried out chevy's LV 1.1 as well, as others seem to have success but it was still lower than the nexus 2.2 so I am back to the 1.25 ulv. I have no reason to complain, the mod runs super well and is stable, and it runs great on this kernal.

Running Chevy ULV 250/1200 on BB 0.4. Other kernels have not seemed as stable or as snappy and worse battery life.

Idle temp is 84.2F! Linpack 18.6, Quadrant 1586
Fully loaded Sweeterhome2 (28 widgets, 93 apps, 600megs free SD space). Battery life is good - can easily get over a day if I let the phone sleep.

Where are you getting the Deodexed Virgin from? It's not in his release post.
