I tailed /var/log/httpd/error_log and ran the PHP script but nothing showed up in the log.

If php -v is slow then it's either load, IO wait, or something with your php modules.

What do these output on the slow system?

Code: Select all

time /usr/bin/php /usr/local/nagios/libexec/check_nagios_performance.php ahc15
time /usr/bin/php --no-php-ini /usr/local/nagios/libexec/check_nagios_performance.php ahc15

What is the full output of these commands on both servers:

Code: Select all

php -i
It's likely a php module causing it since without the ini file it's fast.

Hi,

I've PM'd the output from both servers of

Code: Select all

php -i

You can try something like this:

https://blog.nexcess.net/diagnosing-slo ... achegrind/

What is the output of these commands on both systems?

Code: Select all

ls -l /etc/php.d
The only other way I know would be to remove each extension one by one until you found the offending module that is slowing it down.

This might make it easier, run this command from the slow one:

Code: Select all

time php -n -d curl.so -d dom.so -d fileinfo.so -d gd.so -d imap.so -d json.so -d ldap.so -d mbstring.so -d mcrypt.so -d mssql.so -d mysqli.so -d mysql.so -d pdo_dblib.so -d pdo.so -d pdo_mysql.so -d pdo_pgsql.so -d pdo_sqlite.so -d pgsql.so -d phar.so -d posix.so -d snmp.so -d sqlite3.so -d ssh2.so -d sysvmsg.so -d sysvsem.so -d sysvshm.so -d wddx.so -d xmlreader.so -d xmlwriter.so -d xsl.so -d zip.so /usr/local/nagios/libexec/check_nagios_performance.php ahc15
Then remove one of the -d NAME.so entries and run it again, keep doing it until you find out which one is causing the slowness.

Then only other way I know would be for you to remove them from

Code: Select all

/etc/php.d
one by one but that will affect your web server as well.
