Chapter 12 - Reporting Performance Testing Results
s
Average Throughput
­ Four measurements of average throughput are provided:
passed command throughput, failed command throughput, passed response
throughput, and failed response throughput. This represents the throughput of an
average virtual tester.
s
Time Spent Waiting
­ The total time spent waiting for responses, given both in
seconds and as a percentage of active time. The time spent waiting is the elapsed
time from when the send command is submitted to the server until the server
receives the complete response. The time that an
http_request
spends waiting
for a connection to be established is counted as time spent waiting.
s
Time Executing Commands
­ The total time spent in executing commands on the
Agent computer. This measurement is provided both in seconds and as a
percentage of active time.
The time spent executing VU emulation commands that access a SQL server is
defined as the elapsed time from when the SQL statements are submitted to the
server until these statements have completed.
The time spent executing VU emulation commands that access TUXEDO
middleware is defined as the time to execute the specific ATMI primitive until it
succeeds or fails.
s
Time Spent in Input
­ The total time spent sending virtual tester input to the server.
This measurement is provided both in seconds and as a percentage of active time.
The time spent by VU
http_request
and
sock_send
commands in sending
input to the server is reported as time spent in input.
s
Time Spent Thinking
­ The total time spent thinking, both in seconds and as a
percentage of active time. The time spent thinking for a given command is the
elapsed time from the end of the preceding command until the current command
is submitted to the server. This definition of think time corresponds to that used
during the run only if the TSS environment variable
Think_def
in the test script
has the default LR (last received), which assumes that think time starts at the last
received data time stamp of the previous response.
If any VU emulation commands are executed that access a SQL server, the Command
Usage report includes:
s
Rows Received
­ Number of rows received by all reported
sqlnrecv
commands.
s
Received Rows/Sec
­ Average number of rows received per second. Derived by
dividing the number of rows received by the active time
