Rick As I said before I always found that the cheep crimpers were more reliable than the more expensive ones. the expensive ones have a very high rate of failed crimps the cheap ones as long as you practice with them a bit they are nearly 100% reliable.
Rubin here is a good place to start http://man7.org/linux/man-pages/man7/sched.7.html Also at the bottom are links to manpages for tools like chrt which kind of works like nice and renice. in addition you may want to read up on the io schedulers as well https://www.kernel.org/doc/Documentation/block/switching-sched.txt
also if you really want to get into performance tweaking here are a few other things you should read http://tweaked.io/guide/kernel/ https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/Performance_Tuning_Guide/index.html http://linuxpoison.blogspot.com/2009/10/setting-io-scheduler-for-maximum.html https://www.kernel.org/doc/Documentation/block/cfq-iosched.txt https://www.kernel.org/doc/Documentation/block/ioprio.txt https://www.kernel.org/doc/Documentation/block/deadline-iosched.txt http://wiki.centos.org/HowTos/Disk_Optimization
