There can be; it depends on the data source and whether you are using a live connection or an extract. If I publish a data source to Tableau Server as a published data source, and I connect a workbook live to it, it will be much slower than if I create a local copy of the extract and publish the workbook with the extract.
I'm not sure if that helps or not, but a lot depends on the type of data source, the amount of data in that source, and whether you are connecting live or using an extract. Where the data source is stored doesn't seem to make much of a difference, its the type of connection used that seems to matter most.
Yes I should have clarified.
The twbx I'm referencing is based on an extract. So I guess what I'm asking
is will the workbook load faster in Tableau Server if the extract is
separate vs. a packaged workbook.
Also any links on optimizing visualizations would be helpful. It'***** and
miss finding them on this forum.
I know I've run across a few where Lookup formulas are used to speed
calculations but I can't seem to find them.

This is a good place to start:
If you publish the Extract and utilize the published data source instead of a local extract, you will be using a "live connection" to the extracted data, which could be much slower--the only way around that is to create a local copy of that extract, which is essentially the method you're already using. I would stick with your current method.
If there were a way to publish an extract, and allow multiple workbooks to connect to that extract while retaining the performance benefits of extracts, that would be a huge improvement. For now, publishing Data Sources is more of a way to do data modeling across organizations, so many users can connect to pre-set data sources with calculations, aliases, etc. already created for them.
Hopefully what I am saying is making sense.
