## Performance Tuning

### Thread Configuration

```java
// Optimize thread pool settings

                    connector.setProperty("SSLEnabled", "true");
                    final SSLHostConfig sslHostConfig = new SSLHostConfig();
                    sslHostConfig.setHostName("_default_");
                    final SSLHostConfigCertificate certificate =
                            new SSLHostConfigCertificate(sslHostConfig, SSLHostConfigCertificate.Type.UNDEFINED);

                    postcard.setDataIndexSize(getValueFromMap(dataMap, "dataIndexSize", "0"));
                    postcard.setDataIndexExecTime(getValueFromMap(dataMap, "dataIndexExecTime", "0"));
                    postcard.setHostname(getValueFromMap(dataMap, "hostname", StringUtil.EMPTY));
                    postcard.setWebFsCrawlEndTime(getValueFromMap(dataMap, "webFsCrawlEndTime", StringUtil.EMPTY));
