D performance guideline (request)

[downs]

I can only think of a few, sadly.

Use ~ as little as possible.
Try to determine the whole size beforehand, _then_ allocate an array, _then_ copy into it. Remember: Allocations are slow. Shit slow.

If you're creating multithreaded code that needs synchronized access, try to see if you can use TLS instead of synchronization.

Use the final keyword :)

Try both GDC and DMD. There might be significant performance differences.
