Get or compile the "[sqlite3_analyzer][2]" (or "[sqlite3_analyzer.exe][2]" utility program. You can get precompiled binaries from the [SQLite download page][1]. This program is part of the "sqlite-tools-*" packages. Once you have the utility, run it against your database. It will generate information about how much space each of your tables is using, the average row size, the packing efficiency, and so forth. That information might provide new insight into what is going on. If possible, post the output of "sqlite3_analyzer" here.
