Depends on what performance characteristics you want :) The DLR's isolation mechanism is a "ScriptRuntime", and actually only creates one ScriptEngine per language per ScriptRuntime. So you're option #3 would create a new ScriptRuntime to get any type of isolation between ruby-code executions. Option #1 and #2 are really no different, other than that #1 will be warmed up and just compile the code you give it, which #2 will have to compile dependencies. > Really, I'm mostly thinking about 1 vs 2.

Ruby constants, which includes classes and modules, are essentially globals, so they are stored on the global scope, which means they are accessible anywhere, especially between scopes. ScriptScope only isolates top-level locals and methods. _______________________________________________ Ironruby-core mailing list [email protected] http://rubyforge.org/mailman/listinfo/ironruby-core
