.NET tail calls are totally inefficient. Here is a benchmark to measure tail vs non-tail calls: http://codespeak.net/svn/user/antocuni/cli-bench/tailcall.cs Of course C# doesn't allow to specify a call as tail, so I had to manually patch the IL; here is the modified IL version: http://codespeak.net/svn/user/antocuni/cli-bench/tailcall.il And here is the final executable: http://codespeak.net/svn/user/antocuni/cli-bench/tailcall.exe On windows, the tail call is about 10 times *slower* than the normal call, which is by itself 2 times slower than the for loop. ciao, Anto --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "JVM Languages" group.
