Max # of components in Data Flow ?

Hi All -

I need to copy data from a set of 20 tables in one db to 20 tables in another (on the same server). 

I am planning on putting them all in the same data flow so that they can run in parallel. 

I didn't think that there would be any issue, but wanted to find out if there is any performance issues or a way to make sure to optimize.

This is sql server 2008 r2.  Also, i am planning on dropping the indexes on the destination tables prior to the data load, and then recreating them afterwards.

thanks
