OS Multithreading Interview Question:
Explain some disadvantages of multithreading?
Submitted by: AdministratorSome criticisms of multithreading include:
Multiple threads can interfere with each other when sharing hardware resources such as caches or translation lookaside buffers (TLBs).
Execution times of a single thread are not improved but can be degraded, even when only one thread is executing. This is due to slower frequencies and/or additional pipeline stages that are necessary to accommodate thread-switching hardware.
Hardware support for multithreading is more visible to software, thus requiring more changes to both application programs and operating systems than multiprocessing.
