Custom Script - Long Time Execution

Content

Hello,

I have a custom script which fetch contact data from CSV file and generates contact records with customization.

 Rows in CSV file: 99500

Script includes: set_time_limit(0);

Issue: When i execute script from browser, script can generate only 4000 contact records per execution, however i have executed same script on different environment, at this time script generates 23000 records per script execution.

Is there any setting i need to change somewhere?

Please guide.

EDIT:

After looking at log message, it shows:

Thanks,

Monish
