- refactoring of log to ConcurrentLog:
...
jdk-based logger tend to block
at java.util.logging.Logger.log(Logger.java:476) in concurrent
environments. This makes logging a main performance issue. To overcome
this problem, this is a add-on to jdk logging to put log entries on a
concurrent message queue and log the messages one by one using a
separate process.
- FTPClient uses the concurrent logging instead of the log4j logger

because the new PngEncoder had a problem with the PixelGrabber which is

own frame buffer which can be read without a PixelGrabber. This resulted
in ultra-fast and much less memory-consuming transformation. YaCy images
are now generated really fast!

because newbies are scared about the memory consumption in the performance graph and arguments about high memory consumption according to bad knowledge about java garbage collection techniques, the memory display had been removed from the performance graph shown on the Status.html page. The memory graph can still be seen on the Performance page where the memory graph is just like it was.
