Explanation

renice 11 -u joe ann lowers the scheduling priority of all processes owned by users joe and ann. Nice values range from -20 (highest priority) to 19 (lowest priority). Setting a positive nice value of 11 tells the kernel scheduler to deprioritize those processes relative to others, reducing their CPU impact without killing them. pkill -u joe ann would terminate the processes entirely. nohup prevents processes from dying on hangup but does not reduce priority. strace traces system calls for debugging and adds overhead rather than reducing it.
