I'm using LVS-DR and meet a serious performance issue. My LVS runs on a quad core HP machine, ubuntu 10.04 x86-64, 4G Mem.
VIP: 192.168.1.100 Director: 192.168.1.10 RS: 192.168.1.11 Just a test, scp a file from remote client to RS: (1) directly(RS IP): rate is about 100KB/s, a little packet retransmission. (2) via Director(VIP): rate is less than 50KB/s, ant lots of dup ack and retransmission. And it is more slow if the file is bigger. Using TCPDump to capture packets in Director and RS, I find, 1. Packets Director received are normal with order 2. Packets Director forwared to RS are out of order. 3. Packets RS received are the same with Director sent. So, it is Director forwarding packets out-of-order. But I don't know why and how to fix it. Please help me. Thanks a lot!
