Hi Lucky Raspberrypi2 owner ;),

With this new hardware, did you stress HG ?
Can you see if HG manage the multiples cores ?
And last a more general question, Is it useful to have raspberry pi 2 instead of raspberry pi 1 for HG ?

Bye

Hi Nolio,

I can't answer much of your questions yet.

Is it usefull?
It's bloody fast compared to a B+

Didn't test HG yet, I have issues with I2C that have higher priority.

Wibo.

Guys try out latest HG 1.0 r480:

https://sourceforge.net/projects/homegenie/files/testing/

should support Raspberry Pi 2 and I2C as well (no need to enable it in /etc/module since it is based on direct memory access).

Cheers,
g.

I am very curious if the B+ increases speed for HG.  The best test I can think of is saving a backup.  On winsows it takes about 1 second for the backup save window to display.  On a Raspi B it's more like 2 minutes.  Also loading a web page from the B takes around 30 seconds for the first load whereas Windows is significantly faster.  I doubt I'd upgrade, but I'd still like to know what I could expect should I splurge.

Hi bkenobi,

Did a quick benchmark to give some indication on performance.

Rendering HG in a webbrowser:
RPiB+ ~25sec
RPi2 ~9sec

Different revisions and configurations on both Pi's, so it's just an indication.

Wanted to benchmark the backup too, but somehow it's broken.

Regards,
Wibo.

3x faster is definitely notable!  I prefer these type of real world benchmarks to those of theoretical cpu comparisons or benchmark suites.  The other question is whether the system is maxed out during these operations.  I used "top" on my B when loading a page and backing up and found that the system pretty much maxes out on the mono process.

Hi bkenobi,

I think it's perfectly normal when a CPU goes to 100% under heavy load.

I tested it anyway...

RPiB+ is at ~95% and stays long at 95% after the page has loaded.

RPi2 tops at 200% and falls back to 0+% instantly after the page has loaded.

Don't know how to interpret the 200% yet, probably a multicore thingy I don't know of yet.

Regards,
Wibo.
