is the subject of algorithm time complexity only academic?

hi,

i'm curious. is the subject of algorithm time complexity only academic? when was
the last time you calculated the time complexity of any algorithm you've
recently written for any real-world, commercial, live code of any component
deployed in any type of weblogic server application?

please, can you spare 2 seconds to answer this poll?
