Why, in particular, would you expect the sequence to slow down
inserts?  They don't lock the table.

Note that if you're really doing a lot of INSERTs in parallel, you
might find it worthwhile to configure the sequence to cache some
number of entries so that they are pre-allocated and stored in memory
for each session (e.g. - for each connection) for quicker access.  See
the documentation for "create sequence" for more details...
