In this video we will discuss the advantages and disadvantages of multithreading. This is continuation to Part 86. Please watch Part 86 before proceeding.

Advantages of multithreading:
1. To maintain a responsive user interface
2. To make efficient use of processor time while waiting for I/O operations to complete.
3. To split large, CPU-bound tasks to be processed simultaneously on a machine that has multiple CPUs/cores.

Disadvantages of multithreading:
1. On a single-core/processor machine threading can affect performance negatively as there is overhead involved with context-switching.
2. Have to write more lines of code to accomplish the same task.
3. Multithreaded applications are difficult to write, understand, debug and maintain.

Please Note: Only use multithreading when the advantages of doing so outweigh the disadvantages.
