Hello, Are you able to compile and run any java programs?
What is the error you are getting, what is the command you are using to compile it and how does your source directory looks like? You can compile the sample client on other machines, if this helps your development velocity. You can’t really compare native program (curl) speed with Java, but it certainly should not be that different (I mean yes you can, it just does not tell you much). Do you count startup Time? How did you Test Java if it does not compile? Is the only reason you look into HTTPClient the delay you see with URLConnection? Do you have a sample program for that which shows the slowness?

Excuse me on the replyall part, my bad. when I use curl same https connection quickly returns within 2 seconds, ofcourse different cipher is used. Also I am not able to get sample apache httpclient compiled on Ubuntu Linux machine, any link or steps which I can get to make it compile and work will help. code ============= package org.apache.hc.client5.http.examples; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; import javax.net.ssl.SSLContext; import javax.net.ssl.SSLSession; import org.apache.hc.client5.http.classic.methods.HttpGet; import org.apache.hc.client5.http.impl.classic.CloseableHttpClient; import org.apache.hc.client5.http.impl.classic.CloseableHttpResponse; import org.apache.hc.client5.http.impl.classic.HttpClients; import org.apache.hc.client5.http.impl.io.PoolingHttpClientConnectionManagerBuilder; import org.apache.hc.client5.http.io.HttpClientConnectionManager; import org.apache.hc.client5.http.protocol.HttpClientContext; import org.apache.hc.client5.http.ssl.SSLConnectionSocketFactory; import org.apache.hc.client5.http.ssl.SSLConnectionSocketFactoryBuilder; import org.apache.hc.core5.http.io.entity.EntityUtils; import org.apache.hc.core5.http.ssl.TLS; import org.apache.hc.core5.ssl.SSLContexts; import org.apache.hc.core5.ssl.TrustStrategy; /** * This example demonstrates how to create secure connections with a custom SSL * context. */ public class ClientCustomSSL { public final static void main(final String[] args) throws Exception { // Trust standard CA and those trusted by our custom strategy final SSLContext sslcontext = SSLContexts.custom() .loadTrustMaterial(new TrustStrategy() { @Override public boolean isTrusted( final X509Certificate[] chain, final String authType) throws CertificateException { final X509Certificate cert = chain[0]; return "CN=httpbin.org ".equalsIgnoreCase(cert.getSubjectDN().getName()); } }) .build(); // Allow TLSv1.2 protocol only final SSLConnectionSocketFactory sslSocketFactory = SSLConnectionSocketFactoryBuilder.create() .setSslContext(SSLContexts.createSystemDefault()) .setTlsVersions(TLS.V_1_2) .build(); final HttpClientConnectionManager cm = PoolingHttpClientConnectionManagerBuilder.create() .setSSLSocketFactory(sslSocketFactory) .build(); try (CloseableHttpClient httpclient = HttpClients.custom() .setConnectionManager(cm) .build()) { final HttpGet httpget = new HttpGet("https://httpbin.org/";); System.out.println("Executing request " + httpget.getMethod() + " " + httpget.getUri()); final HttpClientContext clientContext = HttpClientContext.create(); try (CloseableHttpResponse response = httpclient.execute(httpget, clientContext)) { System.out.println("----------------------------------------"); System.out.println(response.getCode() + " " + response.getReasonPhrase()); System.out.println(EntityUtils.toString(response.getEntity())); final SSLSession sslSession = clientContext.getSSLSession(); if (sslSession != null) { System.out.println("SSL protocol " + sslSession.getProtocol()); System.out.println("SSL cipher suite " + sslSession.getCipherSuite()); } } } } } =================== Regards Somshekar C Kadam 9036660538 On Thu, Sep 5, 2019 at 2:09 PM Bernd Eckenfels <e...@zusammenkunft.net> wrote: > Hello, > > Certainly you can use the Apache HTTPClient to replace URLConnection, you > don’t need to do anything special on ARM other than having Java Runtime > installed. > > If you have a slow http download changes are high this is caused by slow > CPU, missing random numbers, slow network or server.
