is anyone else experiencing slow Getactivities response time when geting marketo Activities? We have been waiting at least 30  to 40 minutes.

Are you using getLeadActivities() or getLeadChanges()?  The former pulls the activities of a single lead, whereas the latter fetches the activities of all leads.  You could use the activityFilter->includeAttributes->activityType to limit the activity types you wish to be returned in the result.
