Heath, Thanks for your comments. I'm running eZ Publish 3.9.1 at this point. I've tried to enable as much of the performance improvements as possible via a htaccess file (i'm on a shared hosting platform unfortunately):
php_value allow_call_time_pass_reference 0
php_value max_execution_time 100
php_value memory_limit 300m
php_value upload_max_filesize 40M
php_value mysql.connect_timeout 60
php_value mysql.max_links 400
php_value mysql.max_persistent 0
php_value mysql.query_cache_type 1
php_value mysql.query_cache_limit 2M
php_value mysql.query_cache_size 100M
php_value mysql.net_read_timeout 120
php_value mysql.key_buffer_size 500M
php_value mysql.tmp_table_size 16M
php_value mysql.table_cache 4000
Now, I've also removed all the contents from the pagelayout.tpl, and did a remove-template-cache action, here's the result:

Next, I removed template cache again and put back my original pagelayout:

After this, I refreshed the page (so the cache has been generated):

How should I interpret these numbers? And their differences? Is this a memory/CPU/database/harddrive performance-related issue? Also, if I do multiple requests at around the same time (10 or so), the page gets much slower (like 3.8 secs or so per page). How is this possible?
Thanks again!!
