Hi Alan,

I tried using the named activation group as well. But there is no
improvement in the performance.

Assuming you are running in main program and not wasting time running the

Hi All,

I got one more clue.

When i remove the QtmhWrStout API from my program, now the transaction
time
improved from 500 milliseconds to 270 milliseconds. Now i assume the
QtmhWrStout
API sends some response back to HTTP Server which is doing some process
to
send the response back to client, which is where the performance is
getting
affected.

Any suggestions what to do to improve the performance now?

Regards,
Surender K

Better yet don't use cycle program. Make the program a Main program
without
a cycle. It will run faster.

The 2 milliseconds, do not include the time to start (load) the
program,
opening files, closing, etc. Leaving LR off will allow a much faster
reply after the first call.

To find out the total execution time I often open two 5250, in one I
monitor the other one (DSPJOB) in the 3rd line I have CPU time used.
Go
to the other screen, run the program, come back, refresh, there you
have
CPU time used.

Hi Bradley,

I stored the timestamp value in the first and last line of the
program
to
calculate the time taken by Program (Which contains those three
lines).
Its
taking only 1ms or 2ms to complete it. But the tool which i am
using
to
execute the transaction is postman, which says the total
transaction
took
500ms.

I am not sure where the 498ms delay is happening... Any idea
Bradley?

Also, once this performance issue is resolved, I am planning to use
Scott
Klement's JSON Parser (YAJLINTO) and Data Generator (YAJLDTAGEN) to
parse/generate the JSON document.

Instead of using the APIs, have you tried installing Scott
Klement's
YAJL
and used yajl_stdin_load_tree() in your CGI program instead? It
does
use
the same APIs under the covers.

Hi All,

I am getting some performance issue. Your suggestions will be a
great
help
to me and very much appreciated.

Earlier, I was using IWS as web service and trying some POST
method
transactions (JSON as Input and JSON as response, used both
DATA-INTO
and
DATA-GEN for JSON Conversions). It was taking 300 milliseconds
for
processing a transaction.

Now, i thought of using only HTTP Server and using CGI program
calls
to
interact with RPG. I created a new HTTP Server and updated the
configuration to add the CGI program call. Also, I created a
sample
program
which contains only 3 line of code (Line 1 will fetch the input
using QtmhRdStin API, Line 2 hard coded sample response JSON
string
of
100
character length, Line 3 send back the hard coded response
using QtmhWrStout API).

But the CGI program call method is taking 500 milliseconds for
processing
the sample program (Program with 3 lines of code).

Any configurations which i need to take care in HTTP Server to
increase
the
performance?

Regards,
Surender K
