What is the disadvantage of multithreading?

Question

Testing a multithreaded application is more difficult than testing a single-threaded application because defects are often timing-related and more difficult to reproduce. Existing code often requires significant re-architecting to take advantage of multithreading and multicontexting.

What is multithreading and its advantages and disadvantages?

Multithreading is a function of the CPU that permits multiple threads to run independently while sharing the same process resources. A thread is a conscience sequence of instructions that may run in the same parent process as other threads. Multithreading allows many parts of a program to run simultaneously.

What are the disadvantages of a one to one multithreading model?

A disadvantage of the one to one model is that the creation of a user thread requires a corresponding kernel thread. Since a lot of kernel threads burden the system, there is restriction on the number of threads in the system.

What are the advantages of multi threading?

Multithreading allows the execution of multiple parts of a program at the same time. These parts are known as threads and are lightweight processes available within the process. So multithreading leads to maximum utilization of the CPU by multitasking.
