We use SQLite and transactions are very expensive if more than one
process is accessing the DB.  So what we do is what all other database
engines do: run a single process with exclusive access to the DB.  There
is some overhead due to IPC but overall things are much faster.

The reason why several processes need to access the DB is that there are
often several gpg processes running and working on the same keyring.
This needs to be synchronized.  Without the keyboxd we lock the keyring
and all other gpg and gpgsm processes need to wait until they can
continue even with a read.  This multi-process serialization slows down
everything.

Try running Kleopatra with a large keyring with and without keyboxd.  It
makes a huge difference.


Salam-Shalom,
