I just checked your site, and I don’t know why but I am getting very mixed responses, for reference here are some extremes:
time_namelookup: 0,004
time_connect: 0,169
time_appconnect: 0,000
time_pretransfer: 0,169
time_redirect: 0,000
time_starttransfer: 0,342
----------
time_total: 0,707
time_namelookup: 0,004
time_connect: 2,187
time_appconnect: 0,000
time_pretransfer: 2,187
time_redirect: 0,000
time_starttransfer: 3,652
----------
time_total: 4,052
time_namelookup: 0,005
time_connect: 0,185
time_appconnect: 0,000
time_pretransfer: 0,185
time_redirect: 0,000
time_starttransfer: 9,792
----------
time_total: 10,304
The most important one there is the time_starttransfer, as it indicates the time until the first byte arrives.
