Should I submit a rejected paper as it is in some other place so that publication decision comes quickly?
Ignoring reviewers' comments and simply resubmitting to a different journal sounds like a bad idea to me, for a number of reasons,


While some institutions are obsessed by quantity of publications, quality is at least as important for building a reputation (not to mention more altruistically for actually improving the state of knowledge in the field). If the reviewers have advised you on how to improve it, and if they are not obviously talking rubbish, it seems unwise to discard this advice without a very good reason.
It's entirely possible that the new journal may send it to one or more of the same reviewers as the old one did. There are existing questions on this site from reviewers who this has happened to, and the results are unlikely to be good for you if you have not changed anything. The reviewers are unlikely to recommend acceptance, and the editor may be annoyed if advised of what has happened.
Even if it does get published without revisions in the new journal, the previous reviewers are likely to read it, and it won't do your reputation any good with them.
