nginx compression-at-edge (in front of a reverse proxy) compresses some content, not other ?

Hi Igor,

Thanks for the explanation.  I'll, eventually, get around to giving
the capability a try in nginx.  At the very least, the performance
comparisons will be interesting ...

A good description is here, http://drupal.org/project/parallel

Basically, serving various content types in parallel from Varnish
in-memory caches, in particular when memcache(d) is not an option due
to low RAM constraints (on a VPS ...).

The performance boost -- admittedly under the right concurrent loads
-- can be dramatic.

Thanks!
