Hi, all.
We are testing web traffic distribution performance on a web site using LVS.
The environments are as follows;
Linux Kernel 2.2.17-15(Red Had Based)
LVS Kernel Patch 1.0.2
Least Connection
Direct Routing
LB = Linux Box(1)
2xx.x.x.x79 (LB Real IP)
2xx.x.x.x80 (Service IP)
Real Server = Windows 2000 Server(IIS for web)(3)
2xx.x.x.x80 (Service IP)
2xx.x.x.x81-82 (Real IP)
Persistent Connection activated
Wenn we monitored the performance using ipvs, the following results have come
out,
ActiveConn InactiveConn
x.x.x.x 30 900
x.x.x.x 20 600
The problems is that the counts in Inactive Connect just disappeared and did
not go over to the active connections. Reviewing our recent test results using
LVS, it is hard to find ActiveConn counts surpass 50, even though the Inactive
connections increase to 800-900 and even more.
Almost the same results came out when we activated persistent connection mode.
As more connections arrives from clients, ActiveConn did not increase to more
than 30 counts and only Inactive connections increased.
Can you give me answers to the phenomenon above, or heard of a similar result?
