This looks like this:

Page.execute = 20.668s 
i18n_init = 0.299s 
init = 0.370s 
loadLanguage = 0.115s 
load_multi_cfg = 0.274s 
run = 41.985s 
send_page = 41.809s 
send_page_content = 41.156s 
send_page_content|1 = 20.578s 
send_page|1 = 20.578s 
total = 42.354s

This process runs alle the time with 100% CPU:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND                                                                                                                  
 8509 www-data  20   0  106144  49460   9340 R 100.0  0.6   0:04.94 python

See above.

And: It runs much faster for smaller pages.
