Tapestry Performance vs. JSF (FUD Warning)

[Howard Lewis Ship <hl...@gmail.com>]

I hate to resort to FUD, but my "unnamed source" on the JSF expert
group has told me that they have serious concerns with JSF performance
and in fact were actively interested in "Howard's approach" to
performance and scalability.

Not that there's any magic; there's just coarse grained pooling
combined with static structure (and dynamic behavior).
