It is all about patience. I don't care about how much time will it take to get my articles approved as I know that whenever they are going to be reviewed and approved, I will get the same benefits because the credits given to an article are independent of time taken by the editors to review it.
Also, in that time, members get a chance to review their articles by themselves and also update the information if necessary. So, just let them take their time and till then keep writing more articles as the joy of getting the articles approved at the same time is more than getting them approved one by one.
