increasing memory when connections num increase

code

// static connector
lazy_static! {
    static ref connector: TlsConnector = {
     let mut config = ClientConfig::new();
    let der = std::fs::read("certificatename.der").unwrap();
    let serverRoot = webpki::trust_anchor_util::cert_der_as_trust_anchor(der.as_ref()).unwrap();
    // config.root_store.add_server_trust_anchors(&webpki_roots::TLS_SERVER_ROOTS);
    config.root_store.add_server_trust_anchors(&webpki::TLSServerTrustAnchors(vec![serverRoot].as_ref()));
    TlsConnector::from(Arc::new(config))
    };
}

/// Handshake logic for ShadowSocks Client
async fn proxy_server_handshake(
    context: SharedContext,
    remote_stream: STcpStream,
    svr_cfg: &ServerConfig,
    relay_addr: &Address,
) -> io::Result<TlsStream<STcpStream>> {
    //todo:优化
    // let mut stream = connector.connect(svr_cfg.addr().host().as_str(), remote_stream).await.unwrap();

    let target = String::from(svr_cfg.addr().host().as_str());
    let dnsname = DNSNameRef::try_from_ascii_str(&target).unwrap();
    let mut stream = connector.connect(dnsname, remote_stream).await?;

/proc/{pid}/smaps shows some big Rss( which is all Private_dirty)

when I use tokio-tls，the memory seems normal
