I setup a testing LVS-DR cluster, use 1 director with 8 Windows real server.
ALL server running as VMware ESX 5.1 guest.
The director have 2 cores (X7550 at 2GHz), 2 GB memory, Debian 6.0 with
The Windows server have 4 cores (X7550 at 2GHz), 4GB memory, Windows
2008 Standard SP2.
Linux use vmxnet3, Windows use Intel(R) PRO/1000 MT, all use default
driver with default settings.
When I running load testing against VIP from 4 client machines, 2
JMeter instance per client machine,
i.e. 8 JMeter instance, I got about throughput is 8390/minute.
Then I running one JMeter instance access one real server (of course,
this is not cluster), the total
8 JMeter instances can get up to 9440/minute.
That's said, when I use LVS-DR, I got 12.5% performance degrade.
Any suggestion ?
