Blynk takes 3-4 seconds to connect to server

I found the problem.

This line cause the 5secs delay:

blynkkk/blynk-library/blob/b622d1e2c6ce38579f3b9f281c2854e1d7d140ac/src/Blynk/BlynkProtocol.h#L208


} else if (state == CONNECTING) {
#ifdef BLYNK_USE_DIRECT_CONNECT
    if (!tconn)
        conn.connect();
#else
    if (tconn && (t - lastLogin > BLYNK_TIMEOUT_MS)) {
        BLYNK_LOG1(BLYNK_F("Login timeout"));
        conn.disconnect();
        state = CONNECTING;
        return false;
    } else if (!tconn && (t - lastLogin > 5000UL)) {
        conn.disconnect();
        if (!conn.connect()) {
            lastLogin = t;
            return false;
        }


#ifdef BLYNK_MSG_LIMIT
        deltaCmd = 1000;
#endif
        sendCmd(BLYNK_CMD_LOGIN, 1, authkey, strlen(authkey));

If I change 5000UL to 1000UL delay reducing to 1sec.
