Author insertion becoming slow

is it some logging information that is being written into some file at the end of some transactions
(each intsall is one transaction for me)

the data directory is containing these folders..

base/ pg_clog/ pg_ident.conf pg_subtrans/ PG_VERSION postgresql.conf postmaster.pid
global/ pg_hba.conf pg_log/ pg_tblspc/ pg_xlog/ postmaster.opts

it seems that some info is going into pg_xlog,
is that taking time ....?

thanks
regards
