Gandiva expression evaluation time

Hi Dremio Team,

we are running some complex query in dremio and based on query profile most of the time is spent in expression evaluation.
total execution time: ~5 mins
gandiva expression evalation: ~4 mins (with 8 executors. each thread gandiva evaluation time is in 6 digits)

Are there any ways to improve the performance for these kind of queries?
