Does anyone know the average time to upload a list of 100,000 contacts (30 MB) into Marketo? Is there a limit to the number of records we can upload at once or the file size?

Hi Harish, this question is highly variable because we don't know how many fields are being associated with the records, and what the resulting smart campaigns are that will be triggered by import. All of those things will slow the creation of the new records to some degree. I would leave yourself a couple of hours, and air on the side of caution if you're going to be planning a mailing or something else right away. You really want the records to be able to do all of their data management that you have in place, and get "settled" before you start to prepare a send.
