Im trying to make an app, that i can download my mails from my account.

For the test i have 4 mails, total 200kb. When i download the mails, it takes 30 secs.. aprox.. A LOT! and i dont know how to improve the velocity.

Thanks!

The code that i use to download is this:

ns = networkstream from a TCP, buffer 8192.
private string getemailtest2(int indexservidor)
{
StringBuilder resp1 = new StringBuilder();
bool begin = true;

        int compa = 8193;
        System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
        while (true)
        {
            byte\[\] dataaleer = new byte\[8192\];
            if (ns.DataAvailable || begin)
            {
                int a = ns.Read(dataaleer, 0, 8192);
            }
            resp1.Append(enc.GetString(dataaleer).Trim('\\0'));
            if (begin)
            {
                compa = Int32.Parse(resp1.ToString().Split(' ')\[1\]);
                begin = false;
            }
            int leng = enc.GetBytes(resp1.ToString()).Length;
            if (leng >= compa)
            {
                if (!ns.DataAvailable)
                {
                    break;
                }
            }

        }
        return resp1.ToString();
