Hi,

        Some additional points about this.

1. The Java code using JMH is quite simple. This could be improved with more details

2. I have used 'R' to parse the output of JMH using Hadley Wickham's ddplyr package. ggplot is used to draw the graph. I have to add more details to the graph. I think SE or standard error bars will be shorter if there are more sets of measurements.

       In fact ddplyr's pipes are so powerful that the code used to parse and get the iteration details is just this.

library(stringr)

library(dplyr)

 

data <- read.table("D:\\jmh\\jmh.txt",sep="\t")

 

final <-data %>%

        select(V1) %>%  

        filter(grepl("^Iteration", V1)) %>% 

        mutate(V1 = str_extract(V1, "\\d+\\.\\d*"))

Thanks,

Mohan
