About using multi-thread to execute ipl to submit file

I submit file like this:
In my c++ program, using multi-thread to execute ipl, the ipl include create file and submit file, and now I found, if I execute ipl serially, every ipl needs 9 seconds, so I think if I execute it by multi-thread, it maybe in 20 seconds at most totally, but it was 45 seconds in fact(12 ipls),

I want to know whether there are some advices or somewhere need to improve?

Did you ever stop to think that maybe there might be issues with the Perl code in the ipl scipts?

Since you didn't post the Perl code, there's not much we can provide in the way of suggesting improvements.

In addition to what Ghoti already mentioned - even if your multi-thread broker and an ipl it executes are letter-perfect, you still have a bottle-neck.

It is iwserver. For example, same store "submit" is a single-thread operation. If one is already in progress subsequent Submit request is re-tried
'submit_retries' number of times, default is 61 (once a second for over 1 minute)

sorry, it is my mistake, the submit is not the "submit", it is "deploy", the ipl execute "iwodcmd start" to deploy the file to the web server.

And I made 12 .bat file which execute ipl, and select all and press "enter" button to simulate multi-thread executing, and the result was 35 seconds, less than 45 of multi-thread , but I think it is not a satisfied result .

Are they deploying to the same receiver or different receivers ?

You provide no Environment details, no code whatever and no logging of any sort. All we know is
that you "[...]press 'enter' button to simulate multi-thread executing". That's certainly important.

Basically, your post translates to "Hey, guys! My code works slower than I expect. Can you help?"
Do you really expect anything useful in return?
