Configure Kernel Karameters
|
|
The programmer might be required to tune some of the kernel parameters so that the application can scale at runtime. If that's the case, some of the important kernel parameters to consider are threads-max (maximum threads per process), shmmax, msgmax, and so on. The list of configurable parameters is available in /proc/sys/kernel. The parameters can be configured using the /sbin/sysctl system call. The threads-max parameter can be particularly important if you are porting a large multi-threaded application.
