BUT: a) this is not necessarily indicative of "what will be" because v4 will certainly see significant changes before it stabilizes. i'm also using a variety of flags just to get it to build, and can't say with certainty what is enabled/disabled at the moment (not all valid combinations build right now). e.g. i might have syncing turned off in the v4 build (but certainly don't in my v3 build). b) my tests which use auto-increment/last-row-id are disabled for v4 (it doesn't yet do those), so those tests inherently have a few fewer calls into the db (but not enough fewer to account for a 25x speed increase). In other words, what i'm seeing might just be a fluke of nature. > How does the compiled size compare with SQLite3? The sized on my machine can't be directly compared because i've only got v4 building as a static lib, but the current static lib sizes on x64 Linux: libsqlite3.a 5214256 libsqlite4.a 3753496 but again, that is not necessarily any indication of what it will look like in 13 hours or 6 months. Nor does it give any hint about what the different will mean for clients linked to it. -- ----- stephan beal http://wanderinghorse.net/home/stephan/ http://gplus.to/sgbeal _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
