Kano Speed normal or slow

Hi there,

I wonder how fast your kano Computers are. As I don’t have any experience with the Pi I can’t compare. In general using Apps everything works fine BUT If we use Internet it takes really time to build up the site. I’m talking about 30 - 60 sec.
Our Internet works great with all others devices. Is it normal that PI is slow in the Internet?
Thanks for answering.

I agree. It takes a long time for the internet and Youtube is always buffering.

Thanks! At least I know it’s not a Bug.

Hi my Kano it’s very very slow too… I have antoher raspberry with raspbian and is more fast than kano. I think that there is a big problem here.

Hi @Cyril,

Web performance on the Raspberry Pi is not as fast as you would find on other, more powerful devices - some of this is software (the way Chromium caches to the same memory card that the OS/applications are running from has an impact), some is hardware (specification of the Pi itself).

Googling around throws up folks with similar questions, and solutions including different browsers, and faster memory cards… things to explore for sure!

Hope that helps


Hi, I have just installed Kano and also find it incredibly slow. I can’t seem to get anything to load. The screen freezes. I have re-installed a few times and still get the same problems. I am running a 3A+

Any suggestions as to where I am going wrong?


Hi Richard,

We don’t have a build of Kano OS developed for the 3A+ unfortunately - your issues may be caused by the 50% reduction in RAM when compared to the Pi 2/3

The current 4.X.X builds were developed for the 3B, with its 1GB of RAM.

The older 3.X.X builds, were developed for the Pi 2, that also has 1GB of RAM.

Hope that helps


Hi chris, when you say maybe faster sd cards… what is the speed of the sd card that comes with the kano Touch Kit?


I believe the stock Micro SD card we use is a class 4 (6mb/s)

Hi Chris, I just upgraded microSD to class 10, and it’s still very slow. Any idea when and how this is going to be solved? Thx.

@Daikon The Raspberry Pi 3 is a pretty slow computer and aside from changing to a faster microSD card there’s not much you or Kano can do about it.

I did some web searching and found that this card was highly recommended for the PI. – SanDisk 32GB microSD Extreme Pro 100MB/s A1 4K U3 32G SD microSDHC SDSDQXP-032G-- You can get them on Ebay for under $12 with free shipping. I have used them on our three Touch and one Kano stand alone PI . We noticed a nice speed bump on all of them and the 32g is also nice.

Link to the Ebay card.


The 32G is on shortage, so I got 64G from Amazon, delivered today. SanDisk also has USH-II version, doubled the speed for both read/write.

The speed of microSD really makes the difference, so I suspect Kano OS kernel is doing paging on the microSD card?
