Re: elsif chain vs. dispatch

in reply to elsif chain vs. dispatch

Your example is not practical. Dispatch tables are usually defined once outside the code that runs it. I suggest creating a test code like:

my %dispatch;
sub elsifchain { ... }
sub dispatch   { ... }

That's a good point - the dispatch table is created on every invocation, the elsif code variant is only compiled once. The second point is that the split calls actually obscure the test results, not clarify them.

So what I did was to change all the alternatives to return a literal 'A' instead, and to build the dispatch table only once. That's the result:

             Rate    elsif dispatch
elsif    252062/s       --     -73%
dispatch 927942/s     268%       --

I knew I was doing something dumb. Thanks!
