MAX limit of file descriptor

[horseriver]

 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 ?
