Re: Reg: IBMi Webservice HTTP Server Performance Suggesstions

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
