That'll be why it is so quick.

I'm using mlocate with an up to date database of 525MB

I guess that's why it takes so long.

For the benefit of others I post a corrected version of my locate cacher 
(kept in /usr/local/bin/locate) - the one I posted recursed itself!

#! /bin/bash

ARGS=`echo "$*" | sed -e "s/[^a-zA-Z0-9]/-/g"`
CACHE=/tmp/locate-$USER-$ARGS
test -r "$CACHE" && exec cat $CACHE

if /usr/bin/locate "$@" > "$CACHE.tmp"
then mv "$CACHE.tmp" "$CACHE"
     exec cat "$CACHE"
else r=$?
     cat "$CACHE.tmp"
     rm "$CACHE.tmp"
     exit $r
fi
