The Throughput graph shows the amount of data in bytes that
the Vusers received from the server in a second. When we
compare this with the transaction response time, we will
notice that as throughput decreased, the response time also
decreased. Similarly, the peak throughput and highest
response time would occur approximately at the same time.
Throughput (requests per min, red) grows until CPU is
saturated and then remains constant - the CPU is operating
at max throughput. Once CPU is maxed out then response time
must increase with load. In our case it increases
predictably linearly with load. A thread-per-request system
would drop off as load increases since the CPU has to spend
more and more time context switching threads and not doing
If the response time increase with the throughput all the time it means the system is not stable, and it should be looked at, since the whole point of performance testing is to keep the system stable although you are applying a high load.
Script is working fine in Vgen.. but while running in
Controller a error is throwing as
"Action.c(59):Error-27995:Requested link(Text=My account")
I searched and it is pointing "web_link(...)" line. Plz
help me regarding this.. if any.. Thanks
I urgently need a substantial answer for one Q on Vusers -
Performance Center. Hope you could help me.
Q : My application is intended to undergo soon the load
testing with performance center. The Vusers we planned are
100. But the dev team says that we should use 100 different
UserID/Password's & each Virtual user should login into a
different account while testing.
Firstly, is this required ? my application can handle
multiple logins for the same userid/password, hence is it
mandatory to use 100 different account when we can do the
same test with one account. If so, for 1000 Vusers we
cannot use 1000 logins right ? I need substantial info to
prove my point.
Secondly, is this possible to assign a different userid/pwd
to each Virtual user ?
Thanks in advance & awating your reply
