20070619 is definately faster than 20070426. In fact, it is generally
faster than Aleph at Aleph things (because I fixed the memory leak
that made both progressively slower). It is a some 20-30% percent
slower than pdftex at doing pdftex things, but that has been true
from the start and AFAICS, it is caused more by the extra work done
by the Omega code than by anything else.

I doubt you can gain much. One of the reasons why this snapshot took
such a long time to come about, was exactly because of extensive
profiling and refactoring. Once LuaTeX is 'up to steam' (after one or
two text pages), memory (de)allocation is basically controlled by a
dozen dedicated avail lists.

"No route to host"  sounds like a local network error on your side.
It resolves nicely over here, and the IP address is

Good luck,
