With one run through you should be able to get on average 100 linen cloth and about 15 to 20 green items. If you use all the linen cloth and make green items in tailoring. Then you disenchant all your green items, you should reach about 40 to 60 strange dust. If you sell them in the auction house for about two per stack then you will have to sell World Of Warcraft Gold, just on strange dust. These mobs are fairly easy to kill and yield a decent amount of green items, while also having good vender trash items or gray items for those who do not know. Most times these mobs are being killed so you might have a hard time finding the right rhythm. These mobs do have a fast respawn rate so usually by the time you are done with your med break you will be back up and killing as many as you can.
