The ultimate performance of LVS depends on hardware that LVS runs on. An ordinary box with a single Pentium III and 100Mbps NIC card can handle thousands of connections per second.

What's LVS?
LVS stands for Linux Virtual Server, which is a highly scalable and highly available server built on a cluster of real servers, with the load balancer running on the Linux operating system. Users interact as if it were a single virtual server.
Is LVS software free?
Yes! All LVS software is released under the General Public License (GPL).
Is there a FreeBSD port of LVS software?
Yes, there is a FreeBSD port of IPVS, which supports the LVS/DR and LVS/TUN methods now. See the LVS On FreeBSD page for more information.
How is the concurrent processing performance of current LVS software?
The ultimate performance of LVS depends on hardware that LVS runs on. An ordinary box with a single Pentium III and 100Mbps NIC card can handle thousands of connections per second. We have heard that a powerful box with good hardware and kernel tuning achieved 50,000 connections per second.
Can LVS handle more than 1 million simultaneous connections?
Yes, LVS can handle much more than 1 million simultaneous connections. One connection just costs 128 bytes in the LVS box, so an LVS box with 1G memory can handle more than 8 million simultaneous connections.
