 So, basically: Because Perl is considerably slower in one single comparison, even though it is faster in 7 others, it gets judged as slower overall?Seems like your graphs up top in the language versus language comparison need to be reworked to make it clear how bit the difference in reality between x3 and 1/3 is, because right now it is deceptive.
 >> Because Perl is considerably slower in one single comparison <
 Note the word "considerably". There is only one single task in which perl takes a considerable amount of time longer than Ruby.
 Another addendum, i'm not sure i'm getting what's happening here:If i calculate the average of the time perl took divided by the time ruby took, i get this:((226/724)+(5.35/16.8)+(3/9)+(2750/3960)+(1120/1368)+(3236/3837)+(30.5/35.8)+(939/618)+(263/135)+(662/214))/10 = 1.07Which i understand to mean that perl on average took 7% longer.-----However if i turn this around i get:((724/226)+(16.8/5.35)+(9/3)+(3960/2750)+(1368/1120)+(3837/3236)+(35.8/30.5)+(618/939)+(135/263)+(214/662))/10 = 1.58Which i interpret to mean that Ruby took, on average, 58% longer.------These things contradict and i made some mistake here. Can you clear up what i should've been doing?
 >> i made some mistake here <
 Ok, i don't get it. Can you show me the formula i should be using?Or even better: Try to explain in detail why on the overview page perl is claimed to be slower than Ruby, when in a direct comparison it is not.
 You don't know how to calculate the median?
 English is not my primary languages and especially english maths are hard for me to grasp. That's why i am asking you to demonstrate, using the actual numbers for Ruby and Perl, what calculations should be performed to gain the numbers your site is showing.Also, in addition, after reading your link, the situation seems even worse. Using the median Perl outperforms Ruby by ~15%, but the main site does not reflect that at all.
