taking up a lot of memory, and the average application is just starting to consume nearly 100M of RAM. If you are not aware of the memory control, your program memory growth over 1G is very possible. So much memory needs to be recycled that it's no wonder that most of the time the program executes is consumed by the GC. 2 How do we make a Rails application run faster?

-related work. Memory problems are the primary cause of Slow Ruby applications. The 80-20 rule for Rails performance optimization is like this: the 80% increase is due to the memory optimization, and the remaining 20% is another factor. Why is memory consumption so important? Because the more memory you allocate, the more work Ruby GC (Ruby's garbage collection mechanism) needs to do. Rails occupies a large

. Rails occupies a large amount of memory, and each application occupies nearly 100 MB of memory after it is started on average. If you do not pay attention to memory control, it is very likely that your program memory will grow by more than 1 GB. So much memory needs to be recycled, it's no wonder that most of the execution time is occupied by GC. 2. How can we make a Rails application run faster? There ar

Brief introduction Today's applications need to interoperate not only with browser-based clients, but with other applications as well.
