AFNetworking upload image using AFHTTPClient
<p>My question is why <code>AFHTTPClient</code> is slow to upload image. I am using the below code for uploading</p>

<pre><code>    NSData *imageToUpload = UIImageJPEGRepresentation(uploadedImgView.image, 1.0);
    NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:keyParameter, @"keyName", nil];

    AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://------"]];

    NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"API name as you have" parameters:parameters constructingBodyWithBlock: ^(id &lt;AFMultipartFormData&gt;formData) {
        [formData appendPartWithFileData: imageToUpload name:@"image" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
    }];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
         //NSLog(@"response: %@",jsons);

     }
                                     failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {
         if([operation.response statusCode] == 403)
         {
             //NSLog(@"Upload Failed");
             return;
         }
         //NSLog(@"error: %@", [operation error]);

     }];

    [operation start];
</code></pre>
