[Beginner's note] Using Redis as a cache service in the. Net project,. netredis
Recently, due to project requirements, we have deployed redis in the system cache service department and finally had the opportunity to play in actual development.
Under the first use of nhibernate, fancy its level two cache, but found not to turn on the cache, the data is normal, once opened to find a lot of duplicate data, I tried the two cache implementations of NHibernate.Caches.MemCache and
String is one of the core classes in java programming language. It is widely used and widely used.But do you know what is the direct string volume? Do you know there is a string resident pool? The string resident pool can be used to cache the direct

Example one for (Var i=1;ialert (i);
}
This piece of code is too simple, I am embarrassed to take the shot. The result of the code is to pop 1
It would be unwise to begin the process of optimization without first thinking about this Knuth famous saying. However, you quickly write code to add some features, it can be ugly, you need to pay attention to. This article is prepared for this time.
Before starting the optimization, write an advanced test to prove that the original code is slow. You may need to use some minimum data sets to reproduce it slowly enough. Usually one or two programs that show runtime seconds are enough to handle
