| 21 | '''Analysis of SunSpider tests that show little improvement''' |
| 22 | |
| 23 | 3d-morph: Suffering from missing cross-scope access optimization and DontDelete global optimization (9.4% deep time in resolve()). Probably suffering from lack of static type inference (lots of time in jsNumberCell, JSImmediate, NumberImp::toNumber, etc. |
| 24 | |
| 25 | access-nbody: Major factor seems to be lack of type specialization (lots of time in number-related stuff). |
| 26 | |
| 27 | date-format-tofte: Lots of time spent in parsing and code generation for eval. Can codegen itself be optimized? Also lots of time in makeFunction(), a big chunk of this is making the empty prototype for the function object, as well as setting the special properties (prototype, constructor, length), perhaps those coudl be handled in a smarter way. Also function call overhead for FuncDeclNode::makeFunction itself. Perhaps it should be inlined. Also it is suspicious that call overhead for makeFunction would be a bottleneck, is it getting called more often than it should? |
