A better way to set up Java web apps

If you're building a Java web app that you yourself or your organization will be deploying then you can save yourself a lot of trouble by avoiding the whole build-to-war + deploy-to-server approach. Instead, you should build your web app as a normal Java application with an embedded web app server. Don't build a WAR, just compile the code and serve the files out of their source location. This has the following advantages:

• You can code and test iteratively because you don't have to copy files and create war packages every time you make a change. This is similar to what the mvn jetty:run command is being used for by many developers today.
• You run the same exact code in production as you do in development. Hopefully I don't have to elaborate on the advantages of that. Most developers today use mvn jetty:run or similar to achieve a quick, iterative dev cycle. But come time for deployment, they build a WAR and throw it over the wall to be deployed in some app server

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
