After almost two months it was definately time for a new snapshot.

News compared to the 20070426 version:

Are there any estimates regarding the relative performance?

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.

Sounds like something long overdue. I could imagine that this could be an area relevant for profiling, though.

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.

Thanks (now I just need to get my working copy updated without that No route to host: Can't connect to host 'scm.foundry.supelec.fr': No route to host message),

"No route to host" sounds like a local network error on your side. It resolves nicely over here, and the IP address is 193.48.224.170 Good luck, Taco
