If you use cURL to login and store a cookie with CURLOPT_COOKIEJAR, "cookie"); and later retrieve the cookie with CURLOPT_COOKIEFILE the download speed is very low i dont know why this is happening but it's happening.
tested without cookie download speed is normal,but with cookie is somewhere around 7KB maximum

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

here it is a code that reproduce the problem

$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "name");
curl_setopt($ch, CURLOPT_URL,"http://url/login.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'user=username&password=pass');

ob_start();      // prevent any output
curl_exec ($ch); // execute the curl command
ob_end_clean();  // stop preventing output

curl_close ($ch);

$opt = array(
CURLOPT_USERAGENT => "Mozilla/5.001 (windows; U; NT4.0; en-US; rv:1.0) Gecko/25250101",
if i submit this code everything is ok
0.21246290206909 seconds this is the time response but if i add this under it

   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, 'http://url');
   $content = curl_exec($ch);

here is what it does return and it's weird yesterday i had no problem with namelookup_time and today it does seem that it's unable to calculate it... 

Array ( [url] => http://url [content_type] => text/html; charset=utf-8 [http_code] => 200 [header_size] => 244 [request_size] => 227 [filetime] => -1 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 5.878797 [namelookup_time] => 2.6E-5 [connect_time] => 0.06947 [pretransfer_time] => 0.069475 [size_upload] => 0 [size_download] => 19463 [speed_download] => 3310 [speed_upload] => 0 [download_content_length] => -1 [upload_content_length] => 0 [starttransfer_time] => 5.74344 [redirect_time] => 0 ) This page was created in 6.0242450237274 seconds

hope this will be fixed soon thank you

I doubt this is a PHP issue, if it even is an issue at all.  From the 
PHP side there is no difference between a request with a cookie and one 
without.  That's all inside libcurl.  Try emulating the same thing from 
the command-line curl client with and without a cookie jar and see if 
you see the same effect.  I predict you will.
