Where is a good place to start to troubleshoot high load spikes? We have a specific blog that seems to trigger loads of 2 to 6% or more when the page is re-loaded a couple of times... this still occurs will all normal plugins (not mu-plugin folder) disabled and occurs with different themes as well.
This blog isn't huge, 70 or so posts, but was recently imported into MU from a single intall.. is there a chance that the import may have been corrupted or something similar? Grapsing for straws here....
WHM is showing the following processes seem to be involved:
Top Process %CPU 54.0 /usr/bin/php /home/tracedef/public_html/index.php
Top Process %CPU 53.0 /usr/bin/php /home/tracedef/public_html/index.php
Top Process %CPU 45.0 /usr/bin/php /home/tracedef/public_html/wp-cron.php
