Hi. I have been having a lot of fun learning picoLisp. Thank you Alex for this gem!
As part of my learning, I converted a simple Ruby program I had into plisp and thought I would share the results. The program (namegen) slurps in two files -- one of firstnames with attributes, the other of lastnames -- then produces a random list of First Last pairs to stdout. The data table sizes are $ ./namegen.l -i Database Size: Surnames = 240471 Firstnames = 23405 Here are results of running the ruby and plisp versions (same machine i7 running 64b Fedora fc19 with lots of memory) # ruby version (ruby 2.0.0p353) namegen.rb -i 0.22s user 0.01s system 99% cpu 0.233 total namegen.rb -n 10 0.25s user 0.01s system 99% cpu 0.266 total namegen.rb -n 100 0.25s user 0.01s system 99% cpu 0.262 total namegen.rb -n 1000 0.26s user 0.01s system 92% cpu 0.289 total # picolisp version (picolisp 3.1.7.0) namegen.l -i 0.16s user 0.01s system 99% cpu 0.171 total namegen.l -n 10 0.16s user 0.01s system 99% cpu 0.174 total namegen.l -n 100 0.22s user 0.01s system 99% cpu 0.230 total namegen.l -n 1000 0.69s user 0.01s system 99% cpu 0.702 total The interesting thing is that the ruby version seems constant over the number of pairs generated. I suspect that might be how I/O is handled. The (-i) version just does the data reading, the others read and write. Not a problem, just interesting. Fun stuff. .. m. -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
