php - Delay in server response, apache2 codeigniter -


noticing long delay in server processing time. application environment is: apache2
ubuntu 10.04 php 5.3 codeigniter 2.1
first call after time causes significant delay
codeigniter profiler enabled , gives feedback
loading time: base classes 2.7587
controller execution time ( home / index ) 7.2188
total execution time 9.9777
there 2 database active record queries both taking less 10th of second.
not using kind of cache.
same page on refreshing yields codeigniter profiler
loading time: base classes 0.0074
controller execution time ( home / index ) 0.1471
total execution time 0.1545

from +9 seconds tenth of second.
time there 2 more database queries (codeigniter session fetch , updtate)
there can modify to reduce time when new session started?

codeigniter in opposite zend lighted. try comment unused libraries.
