Unable to import more than 200 records by using feeds module in drupal 7

Help us to overcome with this problem to unable to import more than 200
records.
I have changed in php.ini which is given as follows. max_exec_time 1000
memory_limit 1024 post_max_size 22M
and then restarted the Apache server at all.But did't get the solution.
I have tried by updating the settings.php(sites/default/settings.php) as
adding
$conf['feeds_process_limit'] = 2000;
Please help us as soon as possible .
Thanks in Advance enter code here
