thanks! Actually , my question comes from network performance ,I want to know ,in per second ,the maximum of tcp connections that can be dealed with by my server. How can I do the test and calculate the connection number , Is it possible that my server can deal with 10k tcp connections per second? what is the relationship between this and throughput rate? Is there document that tells the best optimization of this ? _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
