Is it just me, or is the idea of dynamic kernel tuning (a) unique to Linux
and (b) just too cool for words?  Even on Slowlaris where you had the
easy-edit
file you hadda bounce the box... now it's like hey, database thrashing?  no
problem, blip, have some more memory.  Now, if we could get this together with
AIX's journalled file system..... (can you say, dynamic allocation of unused
disk, dynamic re-optimization of logical space across physical volumes
intrinsic to the OS/kernel, and all with live users on the system, and minimal
performance hits?  talk about your killer app...)
