| 393015 [ryand-ruby z] s = "This is a test string"

| | | | 393032 [code apotheo] . . . unless you have a different default for the method's argument.
| | | + 393029 [code apotheo] That's only because it *does* look cleaner.

| + 393033 [su.comp.lang] One thing you can do is to replace for loops with while loops. For loops
| | 393034 [dniq dniq-on] Hmmm... Thanks! Definitely useful advice!
| + 393051 [shortcutter ] your processing is CPU bound?  If it is IO bound the difference
|   393061 [dniq dniq-on] Yep, I'm sure it's CPU bound: the CPU load is at 100%. The data comes in
|   393066 [josh.cheek g] It creates a Range, which just iterates, not an array. A more idiomatic way
|   393069 [dniq dniq-on] Phew... :)
+ 393030 [dniq dniq-on] I have to tell, however, that string.split() works much faster in Ruby
+ 393041 [botpena gmai] omg, careful w big numbers in ruby..
| 393043 [botpena gmai] using plain fixnum may help, but the jump is still there

| 393064 [echristopher] It might make a counter-based loop internally, but at a higher level
+ 393071 [dniq dniq-on] Tried rubinius and jruby. Rubinius so far is the fastest one, but still
| + 393073 [cremes.devli] The thing you need to know about Rubinius and JRuby is that they both JIT (just-in-time) compile the code, but they need to collect statistics on the runtime profile first. That usually takes a few seconds. So any test that runs for under 10s or so doesn't give the runtime much opportunity to optimize the code.
| + 393476 [headius head] I cannot reproduce. Post your jruby -v...I suspect it's running with
|   393477 [headius head] And your other bench. Again, pretty meaningless.
