Submitting very quickly a revised version of a paper
As long as you don't exceed the deadline, I don't think it really matters - it won't get "more accepted" for being resubmitted quickly. Of course, sometimes it can help getting it into production faster.

However, if you have spare time I'd suggest not rushing the resubmission. While you could get away with taking a day, consider taking closer to a week. Forget about the paper for a couple of days, and carefully proofread it again - both the revisions, and the unchanged parts.
