put these settings in /etc/sysctl.conf you either have to reboot or login-logout -Josh On 06/28/2010 02:30 PM, Charles Brain wrote:
When setting the kernel max buffers for UHD the manual suggests using sudo sysctl -w net.core.rmem_max=<new value> sudo sysctl -w net.core.wmem_max=<new value> I have done that on my system and it has made a huge difference to the performance of my software. I can now transmit my DVB-T signal continuously at 10 Ms/s with no dropouts.
excellent
Unfortunately everytime I reboot my system I have to run the commands again. What is the procedure for making these settings permanent? I am no Linux guru hence the question. I am using Fedora 12. - Charles _______________________________________________ Discuss-gnuradio mailing list address@hidden http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
