DBAmp and Salesforce API call Counts

Like all third party salesforce.com tools, DBAmp uses the salesforce.com api
to send and receive data from salesforce.com. Every salesforce.com
customer has a limit on the total number of API calls they can execute, org
wide, from all tools they are using. This limit is found on the Company
Information screen in the salesforce.com application.
Here are some rough guidelines for api call counts for various operations in
DBAmp:
SELECT against link server tables, SF_Replicate and SF_Refresh –
DBAmp requests data in batches of 2000 records. The salesforce server
may reduce that amount based on the width of the row. Our experience
has been that the average batch size is 1000. So for every 1000 rows of
data retrieved = 1 API call

UPDATE and INSERT statements – 1 api call for each record updated or
inserted.
SF_TableLoader without the bulkapi switch – 1 api call for each batch
of 200 records.
SF_TableLoader with the bulkapi switch – 1 api call for each batch of
10,000 records. If you use the batchsize option, then 1 api call per
batchsize
