what is this process?

hello,

mbp 4 years old, , had battery replaced when 1 1/2 years old. in recent months has begun show definite signs of wearing out, have hesitated replace due cost, , figured i'd deal being tethered power source more i'd to.

couple of days ago, noticed computer whining , getting hot when wasn't doing anything, except firefox running. last night, browsing unplugged - not downloading or running video or music - browsing. , before knew (like in half hour), battery down 26%. same thing happened morning.

have widget called istatpro, shows running process called directorys..., that's consistently taking 92-96% of cpu usage (see right side of attached screenshot), running around 50%.

question is: seem battery issue, or there else going on? how track down problem?
