Generating easy report takes too long (~10-12s)

[svoby1]

Hello,

I have created simple report in JasperStudio (Only one H1 text header and two parameters). Via Laravel 10 rest api I am starting $jasper->process... with above mentioned two text parameters, which I am passing through the API. Route is only behind the basic laravel api middleware. When I run the route for generating report via postman, response time is about 10-12s. When I run the same command (which I got with the output method) in terminal, report is done by 4-5s. In both cases, I have noticed, that java app is opened with some delay. ~3-4s in first scenario, ~2s in second scenario. Also I have tried to use just plain exec() with command from output, but the result is the same.

Anyway, this is also not good performance for such a easy report. Therefore, I would like to ask, why the response time is so long? Thank you in advanced for the help.

I am using Mac OSX 14 (Sonoma), PHP 8 an Laravel 10, java v1.8.

Here is command:
'/Users/svoby/www/localhost/test/vendor/geekcom/phpjasper-laravel/src/../bin/jasperstarter/bin/jasperstarter -v process "/Users/svoby/www/localhost/test/resources/reports/contacts/contact_detail.jrxml" -o "/Users/svoby/www/localhost/test/storage/reports/contact_detail" -f pdf -P firstname="John" surname="Doe"';
