--- Comment #9 from Leslie Satenstein lsatenstein@yahoo.com --- Note on performance Fedora development releases use a kernel with extra debug information to help us understand and resolve issues faster; however, this can have a significant impact on performance. Refer to the kernel debug strategy for more details. You can boot with slub_debug=- or use the kernel from nodebug repository to disable the extra debug info.
====== Replace “with extra” with the word “containing extra”. The debug information is not next or beside the kernel, it is within the kernel. ======
