[Q] Hd+ extremely suggish

[View92612]

I actually started using the Nook HD+ with CM10 on SD.

Thanks for sharing. I work in IT and one of my responsibilities is performance tuning. (also I'm very interested in it being a former presales engineer.) So I always wanted to find the root cause. Since you were running CM10 on SD, I can totally understand the poor performance.
I also encountered very bad performance(including benchmark results) when running both CM10 and 10.1 on SD card.
I believe it was mostly caused by the SD card.

Battery life for what it was mainly intended (reading stuff and light apps) is great, but playing Flash and 3D games seems to be the main killer.
I think the issue is 2.1, but perhaps they cut corners with ram and flash speed?

The CPU is weak and 1920x1280 resolution kills the battery life. Much stronger CPU/GPU are required to drive the high resolution in 3D games. Nexus 7 has 4 cores(and a 5th battery saver core) so it is to be expected that 3D games would run better on Nexus 7.
In multiple benchmarks it is clear that Nexus 7 leads the Nook HD+ on CPU performance by far but IO(disk) performance is actually comparable.
(take Antutu for example, 566 vs 555, almost identical) I ran 3D benchmark Nook is 20% slower in FPS from Nexus 7.
On web browsing Nook HD+ is actually the same or better than Nexus 7 with CM10.1. (removing all the unnecessary overhead in stock rom)
Also I suspect the tuning parameters could have been set differently in stock and CM10.1. I didn't compare but the reality is that you can't always run in full performance while also having the longest battery life.

Fast response, higher resolution = more battery consumption, more heat

Long battery life = relatively slow or big battery and/or relatively less heat

I'm actually surprised DH4 would be playable on Nook HD+, it is a 1GB game with lots of data and animation.
I have stopped playing it, though. I bought Nook mainly for reading and Web. My goal was to read e-books instead to save space and maybe some trees.

Larger data games load slow, but play fine overall (random stutter aside). MW3, Nova 3 and the GTA games are examples. They play smooth, but stutter occasionally, without a set pattern other than apparent data access. This and games that load into memory without apparent data access suggests there is another bottleneck going on. Perhaps an issue due to slow flash or memory channel issues. This would also explain the very slow loading of a lot of apps and games that are bigger than 50mb. I notice a huge load speed difference, even compared to the TF300. The Excite 7.7 is the fastest device for loading I have used. Strange, considering a Tegra 3 like the TF300.

The more I think about it, I am getting another HD+. Makes a great comic reader, movie player and game emulator device (especially at $180). Even with 2.1. Will probably start though from scratch with 10.1.

I remembered there is one scenario in DH4 that would lead to stutter. It is very consistent and not random at all. That is when there are a large number of monsters and animations on the same screen. Especially there is one type of monster that would spawn additional monsters with special animations. My solution was to quickly eliminate the monster with animation and the frame rate would go back to normal. Nook is definitely not a device for high end games if you expect smooth performance. I think it would run fine with games like Chaos Rings that have beautiful graphics but only limited animations. The games you listed seem to be more demanding than Nook can handle...

I just ordered another and hope using 10.1 out of box will not have the stutter issues or the slooow load times. For perspective, I had the Razr and it has a 4430 with 1gb ram. It did not stutter beyond the usual Android expectations and loaded apps fast. No stutter while loading data in games either.

Of course, a lot less pixels for the gpu with the Razr, which would explain why MAME plays fast on the Nook (cpu heavy) and some 3d games might have issues (gpu heavy).

None the less, app and data loading should be at least as fast as the Razr, since not gpu or display dependent. Something else is going on with the Nook to cause the slow app loading and data load stutter.

Games like Nova 3 and MW3 play fine until they start loading data and the stutter begins. Also happens when the library sync starts. I will not miss that intrusive process at all. Poorly executed process by the Nook devs.

I recently installed verygreen's cm10.1 on internal memory on my nook HD+. While the performance has generally improved over stock, there is still a bit of sluggishness throughout the ROM. For example, scrolling thru the play store stutters and is still somewhat choppy. Scrolling thru apps in the recent app list is choppy as you scroll. Transition animations throughout not quite fluid.

For sanity check, are others seeing the same issues. Frankly, performance isn't half bad at all for the $150 I paid for it, but I guess it could be optimize as the ROM develops. Its more than usable at its current state. Just can't expect the same fluidity and performance I have on my nexus 7.

Yeah, I'm seeing exactly what you are seeing. There's a general sluggishness in the areas you mentioned, specifically scrolling settings, Play Store and my launcher transitions. I've enabled force GPU rendering and disabled hardware overlay and that seems to help but unfortunately, disable hardware overlay doesn't survive reboots, so I have to remember to enable on each reboot. As you said, the rom runs well and is very stable, makes a $150 buck tab very attractive.

I've attempted to port a couple of roms, AOKP & Carbon and both of them were much more responsive overall. So, I'm guessing that the CM10.1 rom may just need some kind of tweaking. Verygreen is an outstanding dev, I'm sure as time goes on, he'll streamline this rom.

As an aside, I'm sure we could certainly use some love to the kernel.

All the Android devices I have now, Excite 7.7, TF300 and S3 do the same thing, especially when updating apps. The only tablet I have used that does it a lot less or not at all is the iPad 4.

Seems it is more an an Android issue. I do know it is less an issue compared to 2.1.

Maybe my issue with a slow market is the 400 apps on my device?

I don't think so. I just checked and found it to be the same on my Nook HD+ with only a few apps. Fast scrolling can be a bit laggy while the pictures are being loaded. I didn't notice this earlier because I very rarely use this feature. To me it's not a big deal but it could be an issue to some users. Personally I only care the most the actual performance of the apps. From my experience web browsing with Dolphin is perfect. Gaming is okay and acceptable but not as smooth as N7. It's probably due to the new play store interface requiring more optimization. I suspect the old playstore UI could have worked better as it was much less demanding.

Unfortunately, I am also having Nook problems, but the ideas presented here have me totally confused. What is "apex" - that does not show on my apps.
What are "stock settings" - I don't see anything about that in my "Settings" folder. I have no idea what the "nova" launcher or the "lightening" launcher is - I just turn on the Nook and it starts up. Sometimes programs crash or I get a message that it is not responding. Is there some manual that explains all these things or should I just get a new Nook?
