I compiled a vanilla 2.4.24 for a 2 processor Xeon.
I set CONFIG_NR_CPUS to 4 (2 CPUs x 2 hyperthreads each).
When I boot the kernel, /proc/cpuinfo only shows 2 cpus (0-1) and performance is bad.
I reconfigure CONFIG_NR_CPUS back to 32. Now it shows 4 cpus (0-3) and performance is normal.
Is this a bug or am misunderstanding how to set this configuration variable?
