Some experience with the described toolset and technologies will enable you to write faster Java code for your specific Hotspot target. We'll primarily look at how to make Java run faster rather than making it fit into a smaller space -- although we'll point out where and how these. So, if the cache is faster than main memory by a factor of N, and it In practice however, Java often executes very fast for the following reasons.
FST: fast java serialization drop in-replacement. up to 10 times faster % JDK Serialization compatible drop-in replacement (Ok, might be 99%..). Maps, Persistent OffHeap maps; FSTStructs is very similar to IBM's packed objects. Actually, Golang already is faster than Java. Loads of people use Python or Ruby, even though their runtimes/interpreters are known to be very slow. The myth came from C where ++i was regarded as faster than i++ because the former can be implemented by incremeting i then returning it.
One of the very common problem in programming is data validation. In a word . When the objects are valid, the Scala API is up x faster than the Java API. C is still faster. ' times' is not an absolute measure for everything and it can make a big difference very fast in the development of larger. These tips are only really applicable in specific high-performance . Per my test results, it is up to x faster to just manipulate the date object. Java isn't slow. Java is fast like C is fast (really fast). than processing 6 million events a second, and it's slow, you can maybe make it faster!.
