Is this possibly because the shell that Tony is using is evaluating `time zone`?
I can repro, but in my case, the obvious cause is that the `time zone`
portion gets evaluated to an empty string.

Re: [sqlite] Massively multithreaded SQLite queries

In my (limited) experience, it seems that multithreaded SQLite acquires a lock on a shared, in-memory b-tree every time a statement is prepared. It might not be the database read itself, but statement preparation that is causing threads to wait for each other. Your problem might be mitigated if you could compile your queries in advance. ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
