Actually, &quot;fast&quot; doesn&#x27;t mean &quot;performant&quot; (OK, maybe that&#x27;s not a word, in which case I mean &quot;having high performance&quot;), unless you want to also say &quot;speed&quot; means &quot;performance&quot;.<p>Also &quot;utilize&quot; is more specific than &quot;use&quot;: it implies &quot;using for a desirable purpose&quot;.  Consider:<p>(1) This daemon process is utilizing all the available bandwidth.<p>(2) This daemon process is using all the available bandwidth.<p>Sometimes people making up new words do come across as lazy, but you can easily go too far in the other direction, too.
