Try to optimize the mysql settings on your database server. When the database server uses mysql 5.5 or later, then you have to change the mysql defaults for better performance. Innodb is very slow in the latest versions if you do not optimize the settings to use more ram for caching. The problem is not related to ispconfig as ispconfig has no influence on mysql or php performance.
check if xcache is enabled by typing in console : php -v Also check your server load. I use htop ie. apt-get install htop . You can see if there is a process that is hoging your sistem.
In my company i'll use Drupal con my ispconfig servers without any issue. May be the problem is in the connection from the web server and the db server? You tried some speed test between the 2 nodes?
I had the same problem. I got the best results after tweaking mysql parameters, disabling some Drupal 7 modules and enabling a php accelerator (eg APC) For example increase (a lot) the innodb_buffer_pool_size query_cache_size max_heap_table_size key_buffer_size Search for mysql optimization and drupal 7 performance tips. Also you can use mysqltuner and/or tuning-primer
