Latest builds of Opera 10 now include Opera Turbo, technology used to speed up traffic for end users.
Opera Turbo works by passing all data through one of Opera’s proxy servers, which highly compress the data and sends the data on to the user.
Opera Turbo is set to automatic in current release, which will only improve performance if it detects your network is slow.
The latest build also includes an in line spell checker and increases performance.
