Under postgres 7.3 logging is incredibly slow!

I have applied the following settings:

syslog = 2
syslog_facility = 'LOCAL0'
syslog_ident = 'postgres'
 
 log_connections =  true 
log_duration =  true 
log_pid =  true 
log_statement =  true 
log_timestamp =  true 
 
This severely impacted the performance of our production system, a search page which took 1-3 seconds now takes over 30, is this normal?
 
I need to get some performance indicators from our production db, however I cant turn on logging with such performance degradation.
 
Theo
