Credit Card Transaction Time - Are there any logs about the time it took to complete the request?

Have a user complaining of slowness at certain times in the day when they try to authorize a card.

Does anyone know where if there is an existing log to validate this claim or do I need to sit there and watch every day?

Any ideas on how to create a log for this or measure it besides sitting there and watching it?

I noticed there are located on my system in EpicorData folder
\servername\epicordata\companies\CRECreditCardProcess.log

This had what I needed, used an article on notepad++ to bookmark all the lines that had the total process time. Then I got that value out of the string along with the transaction time and did a quick chart to see which times were most problematic.

Thanks!!!
