Dear freebsd people, =A0 in a few days I will install freebsd 8.0 amd64 on my 8GB RAM dual core mach= ine and use the system as a application server. I will install the /usr/por= ts/textproc/weka toolkit, a program written in java. I will use the diablo = jdk port in /usr/ports/java. =A0 Due to the nature of the research I will be doing I will need to max out my= machine for optimal java performance. For example, I will use the=A0-Xmx7g= flag frequently to set=A0the maximun java heap size=A0to 7GB. =A0 Are there any other tweaks I should think of to get as much RAM for my java= programs? Like building custom and small kernel, in order to minimize te size of the = kernel? =A0 Let me know, thanks in advanced, Dino=0A=0A=0A
