Under Linux, why is the CPU load of WebcamSat so high ?
The problem is an implementation issue with the Sun’s Java for Linux. The Sun Java VM process appears to be using a lot of CPU because of the way it is polling the sockets for data, but the Java process should be yielding to other processes on the system. The CPU load seems to be the same whether it’s 1 stream or 100. However, there is a solution ! There are several alternatives to Sun’s implementation of Java on Linux, including optimized open source Java Virtual Machines as well as IBM JRE’s, which comes with RH Advance Server. The specific one that’s been most recommended is called “Blackdown”, and can be downloaded from: http://www.blackdown.org/java-linux/mirrors.html You’ll need to download Blackdown version 1.4.
