Problems with netatalk during update to 1.0

Already tried the backports kernel, it´s a little bit better but 8 mb/s is still terrible.

Yesterday i setted the p-state governor to userspace with an manual setted frequency and the speed went up to 70 - 80 MB/s which is very good.
But i´ve to find a solution for this problem without loosing the pm features.

Any ideas?

I´m using a Mini ITX Board with integrated CPU Asrock Q1900-itx.
The strange thing is that sqeeze makes no problems with it.

The Network card isn´t the problem cause iperf gave me fullspeed in both directions. (about 117mb/s)

OK, just for information.
Now i´m using the the backport kernel which includes the intel_pstate driver which is optimized for intel cpu´s and can handle the states much better.
With this and the performance governor (intel_pstates just have two) the speed is incredible (read 117 mb/s, write 80 mb/s)
The only thing is that the intel_pstate overclocks my cpu automaticly but hope this is no problem because intel_pstate normaly knows exactly what the cpu can bear.

Thanks for your help.

I installed the backports via omv-extra, so the kernel isn´t newer 3.14?
Is this a problem?

It clocks the cpu to 2.9 at turbo mode, so it´s a little bit over the manufacturs default value.

One little other thing.

Got on backports an error containing this error:
firmware: failed to load rtl_nic/rtl8168g-2.fw (-2)

I already have firmware-realtek installed but the version which is installed doesn´t contain the needed driver.
In this package it would be implemented: https://packages.debian.org/jessie/firmware-realtek

So what would the best solution to solve this problem?

Edit:
Already have it, seems the driver wasn´t for backports.
intalled it with apt-get -t wheezy-backports install firmware-realtek

I´m sure in 0.5 it was the just 2.0 ghz for 100%....
It uses the acpi_freq driver and this is get it directly from UEFI.

My UEFI setting can´t edit the frequency, cause mainboard and cpu are together.

I just can do the following:
1.Find a solution to set a speed maximum on intel_pstate.
2.Hope that the cpu can handle it.
3.Go back to 0.5.

Edit:
Do you think it´s just an wrong displayed information?
Cause the minimun is 1600MHz instead of 1300Mhz.

OK....
Now i disabled intel_pstate via kernelflag and changed the governor to ondemand and now i´ve almost the same read/write speed but limited to 2ghz.

What do you think generelly, is the default or the backports kernel better?

Ok, so now i´m writing a review cause i tested pretty much and my expierence can solve much time for other people.

With the backport kernel i was able to reach again 117mb/s read and 60 - 90 mb/s write speed on afp.
First i leave the automatic started driver intel_pstat with performance govenor which normaly is better, but in my case the cpu is detected wrong which mean two things:
my system was overclocked from 2 Ghz to 2,9 GHz, but this could be managed by setting a max cpu scalling. But the other problem was that the minium frequency was also detected wrong (1600Mhz instead of 1300 Mhz)

So i´m now using the backport kernel but with acpi_freq driver, but not with default conservative governor, ondemand did the trick for me.
Seems like they have changed something in the newer kernel on it, so that more p-states can be used which is very important for me.

Thanks for your help.

Maybe a admin or a mod can split this theme in two. (the netatalk theme, and the performance issues theme)
