I'm trying to find documentation to understand the standard volume of data that can be synced between Salesforce and Marketo. I've run into a flurry of issues with the sync recently and it is difficult to determine if this is what I should expect or if there's something critically wrong.


The most I've been able to find are items published by community members or on a tangent topic, such as

How often are SFDC campaigns updated in Marketo? Re: How often are SFDC campaigns updated in Marketo?

"Marketo SFDC Sync can process up to 20k records per hour."

Changes to Marketo Salesforce Sync – Under The Hood

"The backfill process will push data at roughly the same rate as the “Push Updates” rate we get now in the regular sync—somewhere between 7k to 12k records per hour."


I have a case I opened recently where I was told it by Marketo support that it would take 7 hours to process 14,000 records, which is far off from the two items I listed above.


I'm also trying to understand if the standard behavior for updates is to push all updates at once or break it out. During this same incident, I observed that split updates were occurring. To explain, I had a batch campaign with two change data values in a flow. If these were scheduled to update on 20,000 records, the first change data value pushed for all records, then the second pushed for the same 20,000 records again, making the sync work as if it updated 40,000 records.


I've heard that the sync flinches when there are many updates to a record at once that can cause the update speed per record decrease, but again I haven't found any documentation to understand how many updates are considered reasonable versus pushing system limitations.
