Stephan, Most likely the problem has nothing to do with HttpClient as such. Please refer to the 'known problems' / 'troubleshooting' section of the HttpClient SSL guide to find out whether the problem is related to some peculiarities of your JSSE / JDK / target server configuration.
http://jakarta.apache.org/commons/httpclient/sslguide.html HTH, Oleg -----Original Message----- From: Tentrup Stephan (P/BA (INFBA)) [mailto:[EMAIL PROTECTED] Sent: Thursday, February 12, 2004 15:18 To: [EMAIL PROTECTED] Subject: SSL - poor performance Hi, I am using HttpClient (2.0RC3) to make HTTP requests over SSL. At first I specified the keystore with the trusted certificates by the system properties javax.net.ssl.trustStore=/path/to/keystorefile and javax.net.ssl.trustStorePassword=password The performance was good in this case but I wanted to manage the keystore(s) in the java code. So I used the EasySSLProtocolSocketFactory and EasyX509TrustManager classes from the contrib directory and adjusted them to my needs. The functionality is alright but the time cost is very much higher than with the system property method. I added debug messages at various positions to see where the time is lost and I found that between the end of the checkServerTrusted method in EasyX509TrustManager and the end of the method executeMethod in HttpClient the highest amount of time gets lost. I donīt know what is happening between these two points. Any hints?
