Travis,
TPS is not a number that will be determined before hand, the only thing that is \
known in advance is the goal of the performance testing i.e the number of users you \
want the server to support, the performance test determines the TPS and that in turn \
determines the capacity of the server in the number of users it can support.
Anyone looking at the graph should be able to tell what was the capacity of the \
server(TPS), what was the load(Users) and what was the reponsetime, to get a complete \
picture of the Performance test. If only the TPS and the elapsed time are displayed \
what was the load, 1 user? 2 users? 1000 users?
If a user graph can be added above the TPS graph or have it included in the TPS \
graph, that will give a complete picture of server performance with no prior log \
analysis or modeling. It's a suggestion because I like the tool.

Anil,
All Grinder Analyzer does is visualize TPS and response time for whatever test you \
have configured. It's possible you are looking at things backwards. Normally you \
will already know in advance, via log analysis or modeling, how many TPS a given \
number of users will cause. So one normal approach would be to increase the load on \
your server until it cannot go any faster. Then use the TPS you have measured to \
derive how many users your server can support.
-Travis

Subject: [Grinder-use] grinderAnalyzer Question
GrinderAnalyzer is a cool tool.
I have a question about GrinderAnalyzer - Looking at the graphs, there does not seem \
to be a way to determine the TPS for a set of users/threads. A the graph displays \
elasped time vs TPS.
The criteria behind Performance testing is to determine the TPS for X users and to \
see if the TPS keeps increasing as the number of users increase and the point at \
which the TPS saturates for X users and also record response times wrt to TPS & \
users?
Ideally shouldn't the graph be able to show this? Or is there a way to determine this \
from the current graphs?
Thankx,
Anil
