Very slow when try to get result by API

[vishalnthoriya]

Hi i have made small webapp which uses your api to show few sites result

look at here
http://wphostinghub.net/webpagetest/test...edtest.com

here is list of all test with dates and firstbyte value in right column have link to it's test result url.

So when i am doing test vai API it's showing slow like 300-500 for firstbyte but same site when i am doing manually by your site like this http://www.webpagetest.org/result/160224_PD_VTQ/

it's showing faster result with value of firstbyte around 100-200. can any one tell me why this is happens ?

Thank you so much
