	+	====== Ethernet performance with Netperf ======
	+
	+	This page provides information about ethernet performance. Script should generate dokuwiki format.

	+
	+	* Install netserver on your PC
	+	* run netserver

	+	* Download test script {{:kernel:testing:netmeasure.tar.gz\|here}} (quick release)
	+	* Unpack to your petalinux-dist/romfs folder (Check file permission - 755 or 777)
	+	* Please check your kernel hacking (make linux_menuconfig) and disable all options
	+	* Build your kernel with fs (I tested this script on both kernels - MMU and noMMU)
	+
	+	* Boot linux kernel
	+	* check if is netmeasure.sh script there
