Use the URL

to view the
performance report.
Note
You must include a period (
.
) before the extension you defined in the
mime.types
file (in this case,
.perf
).
The report contains the following information:
• Average column shows per request statistics.
• Request processing time is the total time the required by the server to
process all the requests it has received so far. Even on the busiest of the
servers this number will be very small compared to the server uptime.
• Number of Requests is the total number of requests for the function.
• Number of Invocations is the total number that the function was
invoked. This differs from the number of requests in that a function
could be called multiple times while processing one request. The
percentage column for this row is calculated in reference to the total
number of invocations for all the buckets.
• Latency (in seconds) The time Enterprise Server takes to prepare for
calling “send-cgi.”
• Function Processing Time (in seconds) The percentage of Function
Processing Time and Total Response Time is calculated with reference
to the total Request processing time. (The time spent in “send-cgi” (that
is, the time required to fork/exec the CGI program plus the execution
time of the program itself.)
• Total Response Time (in seconds) The sum of Function Processing
Time and Latency.
• Percent column displays of Number of Requests is calculated with
reference to the Total number of requests.
