Hi, I am struggling a bit to understand the maximum connection capacity of a director. As I understood, each connection worth 128Bytes of memory which means a 1GB server can handle more than a Million connection.
Fine. But there is also this Linux "port available" limitation which if I understood correctly would reduce the number of of possible connection to about (65k-1024) * number of real servers. Which can be a bottle neck as the infamous TIME_WAIT connections are counted as part of those connections. I am using a LVS-NAT director so I am not really using local port for each connections which make this second limitation a non sens to me. In theory I could have (65k-1024) * number of real server * number of client IP which anyway would be much bigger than the first memory limitation. Is this correct ? The other question is around kernel tcp parameters. I don't really like to mess around with tcp parameters, but it is possible to limit the effect of TIME_WAIT by using tcp_reuse. Now, I know that lvs handle it's own tcp parameters like time_wait timeout for instance so does it also handle it's own tcp_reuse mechanism ? Thanks for your input.
