Download and Update patch on SharePoint Farm

Microsoft has been released SharePoint 2010 patch update for a while refer to the following links.

• Microsoft Office Updates 
• Updates for SharePoint Products 

then I downloaded the SP1 and August CU updates from the above site. Service Pack1 for many products

1. Documentum Search connector SP1
2. FAST Search for SharePoint SP1
3. FAST Search for SharePoint August CU
4. Office Web Apps SP1
5. SharePoint August CU
6. SharePoint SP1
7. SharePoint Designer SP1

All of their size around ~2GB. the SharePoint August CU size is about 1GB. I though there's a lot of bug in SharePoint.
