Save time by adding your IP address to Trusted IP Ranges, which will allow you to not have to use your security token when loading data with Dataloader.
When accessing the Dataloader you have to append your Salesforce token to the end of your password, and if you make changes to your Salesforce environment, Dataloader does not automatically update, you have to re-login; this means re-entering all your info along with the long security token code…
How can this process be sped up?
First you have to find out your IP address. Go to http://www.whatismyip.com and copy your IP address.
Then, add this as the 'start' and 'end' IP addresses in Security Controls->Network Access
