I am having some performance issues with caching lazily-initialized LOBs. A large amount of time (>25% of total time according to JMC) is spent trying turn the byte[] into a String. Some of our byte[]s can be several MBs large, and this is hurting performance more than caching them improves performance in the first place.

I thought this could be related to https://hibernate.atlassian.net/browse/HHH-11097 but we are using 5.2.13. I have attached the stack trace in the images below. My entity class, which is lazily loaded, is below:

@Entity
public class Payload {

  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private Long id;

  @Lob
  @Column(length = Integer.MAX_VALUE)
  private byte[] payload;

  public Payload() {}

  public Payload(byte[] payload){
    super();
    this.payload = Arrays.copyOf(payload, payload.length);
  }

  public byte[] getPayload() {
    return payload;
  }

  public void setPayload(byte[] payload) {
    this.payload = Arrays.copyOf(payload, payload.length);
  }
}
