How do you make sure your Kindle is running fast?

Hi Kindle Developers' Corner!

New owner of a jailbroken Kindle Paperwhite 2 here

I was wondering, how do you guys make sure that you have enough resources (memory available, CPU available, or even swap space available?) in order to keep your Kindle running smoothly?

The biggest issue I had with the Kindle recently was when I was trying to write in a notes file. I SSH into my Kindle, and from my Kindle SSH into my smartphone and from _that_ session attaching to a tmux session! I make sure to redirect the SSH session from the Kindle to my smartphone to the tty shown my kterm on my Kindle. I do this because my kterm horizontal binary is a little bit broken on my PW2, so its keyboard does not work.

When I do this, I have some moments (somewhat rare) where I have to wait a second or two for some keys to input. When I restarted my Kindle, this improved.

Thanks,

Wilornel

You are seeing the effect of the 'on demand' power/freq governor.

The "CPU Report", KUAL extension has a menu for selecting the governor in use.

If you want to - you can use it to lock the Kindle to its maximum power/freq setting (the 'performance' governor).

But beware - it will eat your battery in a hurry, so keep it on external power.

Hmm would sshing into a different device and showing an external tmux session eat the battery so much? And yes, I'd be glad to have to recharge it once a day (instead of once every few weeks!)

How about once every two hours?

You never said what transport media you where using, so I assumed Wifi.
Which seems to be confirmed by your not pointing out that you where doing this over the USB cable.

Re-read the sentence above the comment about keeping the device on external power, the two sentences go together.

Ans:
It is not so much what you run, but how often and how long during the use time that you let the Kindle go to sleep (the use case you have mentioned, sleep time == none).

I see, thanks knc1! I'll work with it through USB then! I can connect it to my phone with an adapter
