Multi Thread Groovy test step

Hello,

I would really appreciate help with this.

I create a test that compares data between 2 tables with large data return. the script does the job perfectly but it takes very long time to execute as it loops thru hundreds of thousands of records and verify value to value from each column.

I was wondering if there is a way to run the test step groovy script in multi thread instead of doing one value at a time.

thanks in advance!
