What is a good way for excel to test network connection speed to the network drive my excel project is stored on?

Many of my clients have been complaining that my excel project runs too slow (running it off the network). This is because some of the offices have slower connections than others to the network drive where it (and its access backend) is stored.

I think it’d be best to try and write a macro which measures connection speed to where the excel sheet is being run from, and then if it is below a certain threshold I’ll have some sort of warning message telling the user they should download a copy locally.

Any recommendations of how I can do this?

Thanks,

My only idea so far is to output 10,000 repeated characters to a randomly name file in ActiveWorkbook.Path then delete it. Based on the Now() before and after this operation I can estimate connection speed. This has lots of potential issues… full drive, write permissions, balance between runtime and accuracy.

    Try writing a fixed number of characters to the same directory the workbook is stored (Workbook.Path). Do this in a for loop, and have it repeat so that 10,000 characters are written (or whatever number you choose). Do a timing statement before and after. Figure out where an appropriate cut off is in seconds and display a message for anyone that took longer than your cutoff time.
