Causes of Prime Microstutter? (Choppiness)

[tf201]

Not sure if this should be here or in general but I've been researching and looking at some underlying perfomance data about why our beloved Prime's can't browse internets well (click for full tiered list--couldn't copy it here).

1. Nvidia Drivers that aren't fully optimized yet
2. Overly Aggressive Power Gating
3. Slow NAND Storage
4. Browser Parallel Processing Algorithm that is too "passive"
5. Android is still a young os

Any other ideas or observations? Do you think we will see a fix to the native browser stalls?

I can pretty much agree with #5 but since I don't experience the choppiness you describe the premise of the other 4 items may be false. If true, everyone would be having the same problems and that's not the case. I think Mark Tech is looking for causes that may or may not have much to do with reality.

Same question came to my mind. What choppiness?

The nand has been proven to be slow via objective benchmarks vs similar devices. I can post links later. I'd like this thread to lay some ground work on how to address and fix these issues. Perhaps something we can incorporate into custom roms or flash able zips. Every device has idiosyncrasies taking the ostrich approach doesn't further anything IMO but we can agree to disagree on the state of realized potential from the tf201.

E.g. wait for the program to respond with stock browser. If we log excessive nand que length we can start to perhaps surmise causes and fix. Maybe disabling nand cache on the browser could address it if its a nand bottleneck.

Basically the prime is great but I think its not fully tuned yet.

Just a quick note increase SD Block size with SD Booster or similar will improve I/O performance of about 2+ Mbps write and read.

I didn't see any one taking the ostrich approach.

As for the choppiness I also have seen none on my 101, I'm not denying a problem, there just is no problem for me.

The level of concern that you and Mark Tech have noted, is about things that the average consumer would not even think about, and I doubt they would even know what you are talking about.

I'm certainly not a fanboy or an ostrich with it's head in the sand, just someone who turns his tablet on and uses it without concern about:

Nvidia Drivers that aren't fully optimized yet
Overly Aggressive Power Gating
Slow NAND Storage
Browser Parallel Processing Algorithm that is too "passive"
excessive nand que length
disabling nand cache on the browser could address it if its a nand bottleneck.
increasing SD Block size

Perhaps a more technical Forum like, XDA, they are uber geeks and would be glad to discuss: Browser Parallel Processing Algorithm that is too "passive", endlessly with you.

All the above was written in the best of meaning and without rancor.

.25 firmware being tested is aimed at fixing these issues...
