Plugin Time limit 2 minutes

Hello All,

We have a plugin which creates marketing lists in campaign by taking into the existing marketing lists of campaign.

The plugin is giving a timeout 2 minutes error.

I have gone through several questions in the forum and they suggest to use Custom Workflow.

Is there any way to increase the execution time limit of a plugin?

The marketing list contains 10,000+ contacts and i have to traverse through the list to create 6 different marketing lists. As plugin is throwing timeout error, can i use a custom workflow?

Thanks,

Abhilash.
