Hi all, I had made a KLM which mangles the system calls. I want to see the performance degradation of the operating system , when my modules are loaded. So, I just want to know that what is the overhead in calling sycalls. Don;t want tools which test CPU/Memory/FS performance . Is there any tool , which can check performance of syscalls , when klm is loaded. Thanks, Ashish -- Kernelnewbies: Help each other learn about the Linux kernel.
