Hi,
Thanks your LVS program and and I have some questions about LVS.
Question 1:
-----------
It is my Linux Director benchmark result. (using the ZD's WebBench 3.0)
The result is 2 types; one is Requests/Sec. the other is Throughput (Bytes/sec.)
The Linux Virtual Server is Very Good performance !!
By the way, How do you verify the fact of load balancing of LVS ??
I'd like to hear your comment about it.
I want your bechmark test results or program or URL or any clues.
- Note : My experimental environment (text file) and benchmark result(MS-Excel
files) are attached.
- Homogeneous Server :
. Pentium2-300 ->1 Client
. Pentium2-300 ->30 Clients
. Round-Robin (40% increase)
. Least-Connection (60% increase !!) Pentium2-300 * 2EA
Question 2:
-----------
Some LB companys support the adaptive load balancing method.
I have an idea whose scenario is following.
- The agent monitors load - CPU, memory, etc- in the real server
- and calculates the appropriate load value
- and reports the load to the Linux Director periodically
- then Linux Director's ipvsadm adjustes the weight value of WLC or WRR.
What do you think about an "agent" method ?
Question 3:
-----------
The ipvsadm program doesn't well weight adjustment in the WLC...Why?
Mm.., in the ipvsadm source, "mc.u.vs_user.wheght" value is constant ?
