Does anyone have an efficient tree implemented in STM that<br>supports concurrent updates in an efficient fashion? This<br>seems suprisingly hard to implement - a normal binary<br>tree with links as TVar is very slow and does not scale
<br>very well.</blockquote><div><br>I'm just wondering whether it is important for you that all the internal links are TVars. That of course depends on what kind of API you're imagining for your data structure. I would imagine though that a single TVar pointing to the root of your favourite functional tree implementation will be quite sufficient. My guess is it would also be the fastest way of implementing it.
