PHP Strange things happening to curl -

i have project needs fetch data xml api, i'm using php's curl data api. data download follows

• 1 request fetch data, 123kb file
• 1 request data specific info 600 bytes file
• 1..10 request images (max 170kb files)

in order , nested bottom top, data obtained school, activity calendar , image gallery

so see, there 12 curl request top

i have debugged application logic, , delay once data on memory perform operations 3 secs.

the timing obtained curl_getinfo follows

{      "url":"the url",    "content_type":"text\/xml; charset=iso-8859-1",    "http_code":200,    "header_size":222,    "request_size":600,    "filetime":-1,    "ssl_verify_result":0,    "redirect_count":0,    "total_time":0.942642,    "namelookup_time":8.4e-5,    "connect_time":0.179581,    "pretransfer_time":0.17966,    "size_upload":326,    "size_download":12720,    "speed_download":13493,    "speed_upload":345,    "download_content_length":-1,    "upload_content_length":326,    "starttransfer_time":0.576183,    "redirect_time":0,    "redirect_url":"",    "primary_ip":"81.93.213.42",    "certinfo":[       ],    "primary_port":80,    "local_ip":"192.169.233.75",    "local_port":43479 } 

this data encoded json, because putted on log server.

so question why if curl takes 1s response api , logic executed between 2 , 3 seconds response has time of 1 min, next 50s???

one thing notice website runs on godaddy, vps under https , api runs on http, has do?

thanks in advance

resolved, server delaying download of data curl requests, spoke hosting provider , removed delay downloads. curl requests delayed server, not code or curl handle itself. comments.
