Benefits of Multi-Threaded Programming

• Responsiveness
- User interaction in parallel with data retrieval

• Utilization of MP Architectures

• Resource Sharing between Threads (vs. Process)
E.g. Synchronization by accessing shared data

• Economy (vs. Process)
- If the task is the same, why not share the code?
- In Solaris 2, creating a process is about 30 times slower than threads. Context switch threads is about 5 times slower.
