Root mflops?

If you install the updated zanfur kernel, you'll be able to go above 710. I did that for my dad's Eris and it's working fine. Uses the stock lockscreen, too.

Here's the patch: Overclock Patch and update.zip - xda-developers

Yeah, I kinda suspected I could tweak it in other ways (thanks for the heads-up though). I'm not really a ROM flasher or tweaker :eek: (neither term being meant disparagingly or double-entendre' (okay, maybe the latter :D)) since this is my day-to-day phone and I can't afford to goober it. Also, Ivan says he's building 1.1 "for speed" (plus, I think he is waiting for the 2.1 OTA patch being sent on the 16th to grab those code fixes).

Hopefully, after tomorrow I'll feel more free to experiment with some spinners and chrome hood ornaments... Hmmm, is something being released in the wild tomorrow....? (hint: think "X" :))
 
On my eris before root (1.5) i was getting 1.9-2.2. after root with OC this moved up to 2.3-2.5 with aloysius JIT and OC i am getting 5.3-5.5. and with JIT my phone can now run 3d apps without lagging at all (except for ipingpong, though i suspect its just coded horribly)
 
Gads, I check back in here and you guys are still mflopping all over the place. ;)

Ok I just checked mine with xtrROM 3 running at 729/528 and got 2.28, then switched to 729/729 and got 3.18.

This on the quickest ROM that I think I've ever run since I rooted.
 
I still would like some OC guru to explain to me why my xtrROM (and Aloysius) run just as fast unclocked as they do with settings in the 700s.

The mflops go up with high SetCPU settings, but I see no real speed increase.

EE, Ivan's and several others didn't have that effect at all, especially EE3.

Frisco,

I posted (yesterday?) a quick & dirty Linpack test on Ivan's ROM with and without overclocking and got almost identical MFLOPS. I just think that 710MHz (that I'm overclocked at) is too far off from the base 528MHz speed of the CPU to make that much difference (and is therefore a pretty safe speed to overclock at).

I don't remember if Nestor posted any Linpack scores from his Ivan's 1.0 with JIT and Zanfur's OC patch installed (don't know how fast he is overclocked to)... Nestor, you out there? :D

edit: P.S. maybe a ROM developer could weigh-in regarding what the core differences there are between how the ROMs are built, since I think this is almost certainly the key factor in how "fast" a ROM is ("fast" still being the subjective adjective). Many ROMs are "derived" (i.e., from HTC's builds), others are source-compiled, etc. Each of these methods, features, and any optimizations done for/in them must contribute to the ROMs overall speed.
 
Clocked down to 528/245 I'm getting 3.5-3.7. I know Aloy is a bigger rom (not sure about xtrom), so maybe it has something to with that. Kind of like a bigger increase in power is needed to move a bigger load faster.
 
Right now I'm at 768, running e_o 1.0 + zanfur's kernel + jit, and I'm getting linpack scores of 5.0, 4.9, 4.8, 5.0...

At 528, running the same combination, the scores are consistently 3.6.

Without jit, it's about 3.3 at 768 and about 2.4 at 528. The score is definitely proportional to the cpu speed.

As hungryman and I have discussed on xda, we're not seeing a real-world difference from jit, just higher mflops in linpack. Perhaps in froyo it makes a bigger difference.

Keep in mind I'm running Sense, so I have to use the Desire version of jit. Also, most non-sense roms are faster.
 
have you seen the top ranking phones? Someone has their Eris at 15.9....yikes.

I just got 4.3. KaosFroyo V23, no OC.
 
I'm referring more to the perception of menu and app speed not overclocked, particularly in xtrROM and Aloysius Snow (I keep changing my mind about which seems faster).

When I overclocked Evil Eris 3, and saw mflops around 4.2 at 710, it did not have the snap to it that xtrROM and Aloysius do not overclocked even though the mflops go way down in the 2s.

I want to understand why.

The thing you're pointing out, Scarey Alien, about the usable capacity of the CPU (as I take what you're saying) makes sense and is a factor, for sure, but that would make it seem that the xtrROM and Aloysius devs know how to use the CPU better than overclocking. :confused:

Yep...you are right on! :) When I helped andrizoid out the other day deodexing a ROM, he was lamenting the fact that the ROM was, in his words, "heavy" (as compared to his White Widow ROMs, etc.).

The devs must surely have "fat-burning" and optimzation things that actually do make a difference (zip-aligning, compressing, other magic-y stuff :D).
 
Kernel tweaking/development is the area we're probably talking about.

But the boot process is what seems to be the emphasis in linux kernel forum threads on the subject of speed (nearly always comparing to Windows).

I'll read around some more.

Off-topic: did you hear? OTD has rooted! :eek::D:)

What launcher are you using? I am using ADW on White Widow 4.5, and I only get mflops around the 3's or so. I have not noticed any significant difference in performance when overclocking. However, there are some settings in ADW for how long it takes to switch screens and for the app drawer to pop up. I put them at the lowest settings (in milliseconds), and the "snap" was incredibly noticeable. I felt more of a speed increase just by adjusting those settings, rather than the actual SetCPU settings.

A lot of the numbers you see in there are not real, they are spoofing it somehow, most likely with emulators on their computers. Although you will see Moto Droids hitting the 15 - 17 mark but not an eris. And I remember reading somewhere that using linpack is not necessarily a good way to measure the speed of your device. I think Quadrant might be better at measuring the speed of your device but I wouldn't recommend it as it might depress you seeing it compared to other phones out right now.

+1 -- I ran Quadant once after reading about it on another forum...still waiting for it to finish! :eek: [jk...its pretty graphics-intensive, though]

ADW now (on Aloysius Snow).

I did some creative comparisons with the provided Helix and my former fave, LP, along with Home and of course Sense (Sense has a "phone" button, redundant to the real phone button on the bottom left of the Eris, so I moved into other launchers with unbridled glee once I found out the "phone" button was gone on them).

ADW is winning (just getting rid of the confounded "notification bar," which everybody seems to like so much, was a good enough reason to have LP, but ADW has that capability too :)).
 
I am noticing that xtrROM 2.1.1 is beating out Aloysius and xtrROM 3 in mflops and perceived snappiness a bit.

I'm not surprised as it is lighter and not running a2sd, etc.

I doubt if it's my last "favorite," though. ;)
 
Was getting consistent mid 3's on EEv3.0 overclocked to 768, then flashed CELBv2.8, overclocked it to the same and am now getting consistent 5.0X. Definitely a quicker ROM, not as smooth due to the lack of Sense though.
 
Thanks for the post, I didn't know how to measure it til now.

Just ran 10 test and had nothing under 5.2, highest was almost 5.6. Not sure what to do with it.

I am running KaosFroyo v23 OC 787.
