I have made a program for Payroll in Vb.net where i need to upload the attendance of 5000 employees through an excel sheet.
That is, 5000 employees * 30 days so there will be a line item of 150000 in the excel sheet.
My issue here is,
It takes very long time to get upload into my system, the performance of my add-on is very worst.
How to resolve this issue???
