How long does your CRM take to sync to Marketo?

Hey guys, new to Marketo, so I was wondering what people typically see for sync times between their CRM and Marketo. I ran a report for when a contact is created in CRM and then pushes to Marketo. These numbers are for only one of our nurturing tracks for January with close to 29k new contacts created, these are the delays I am seeing:

Under 3 Minutes: 0.1%

3-5min: 26%

5-10min: 13%

10-60min: 13%

1 - 2 hours: 14%

2 - 3 hours: 11%

3 or more hours: 22.10%

Does that seem ridiculous? I come from a Pardot/SFDC background and we would rarely see anything over 3min.

Thanks,

Justin
