Hands-On Software Architecture with Golang

Programming

We already looked at how algorithm and data structure choice can significantly impact performance and scalability. Besides this, other programming source of bottlenecks are as follows:

• Locks: There is no fun in having multiple threads doing something in parallel, only to take a lock and serialize themselves. Consistency is must in a thread-safe application, but you need to consider the granularity of the lock made. A common source of error is making the critical section (the part of code under the lock) too fat; not everything needs to be done with the lock taken.
• Deadlocks: In a multithreaded application, if threads need more than one resource to do the work, getting into deadlocks is a real possibility. Deadlocks can also happen ...
