Performance reduction with rails 5.2

[nikhilsojan]

Hi
I was using axlsx to create a workbook , stream and write to a downloadable xlsx file with rails 4.2. It used to take less than 60 seconds to create a downloadable xlsx file with 40,000 records, along with currency and date formatting. After upgrade to rails 5.2 , no more than 10,000 records can be added under 60 seconds. The total time includes fetch from db, parsing, excel creation and sending for download out of which
xlsx_package.to_stream.read
takes more time than it used to
Is there a reason for the performance reduction?
