I am one of those people, but as I (hopefully) mentioned at the time, I had some other tasks I had to address first (namely, the release of Happstack 7 and clckwrks). However, starting this week I am finally looking at some acid-state related issues. Part of this will be building some tools to help analyze where all your RAM is going. My current hypothesis is that for hackage 2, we should be able to reduce RAM usage by 10 to 100 fold. The size of the data on disk is only a few MB.. I currently can not think of any good reason why it should take anywhere as much RAM as it currently does. So, it must be doing it for some bad reason :) Though, I won't know until I do the analysis. You'll probably see some blog articles as I work out the process. - jeremy _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
