Yes is there are more hashes it runs slower. That is why you see the speed increase after cracking some of them. What the wiki is saying is that if you just run a wordlist on fast hashes without rules its not going to run at top performance but with slow hashes like md5(unix) it will run at top performance because they can not be computed as quickly. So it is best to get rid of as many unique salts as you can to start with. Then that will increase your overall performance.
