Some things are faster, some are slower. .Net is a managed code language, which will make it slower by default. But many of the tools in place have been optimized to run significantly faster.

The System.IO namespace for instance. It has entirely replaced the old File System Object. FSO was a great tool, but was increadibly slow. tediously slow even. System.IO's members are lightning fast by comparison.

.Net also uses GDI+ instead of GDI. Anytime you work with GDI in graphics the smallest mistake can cause huge performance hits. But if you have a graphics intensive app, you are using GDI, and are having performance problems, that could be a culprit.

.Net has a great little tool call Environment.TickCount it will grab the current clock ID and is exceptionally helpful for tracking processor intensive methods with out hindering performance.
