Hi, My question is regarding some detaails that WL has given to plan for how many servers(CPU's) are needed for predicted system load. Can someone help out in clarifying this:

1) In one section of the document(Click below):
http://e-docs.bea.com/wls/docs81/capplan/capbase.html

For a 4 CPU Windows2000 server: It appears to say Max Transaction per second = 80.24 (from lmW1)

2) On the next section it says:
http://e-docs.bea.com/wls/docs81/capplan/capgen.html#1056496
The preferred hardware configuration is Windows 2000 using 4x700 MHz processors.
The Reference TPS is 205, from Table 2-3, configuration number lmW1

I am not sure how they are coming up with the maximum TPS of 205 for a Windows 2000 Box, when the benchmarking says it can support maximum of 80.

Is it a Typo, or am I missing something?

Additionally, in your experience, how many concurrent users can a 4 CPU machine utilize?

Thanks in Advance,

-Avi
