IoUtils.close() operation takes a long time when using implicit SSL -------------------------------------------------------------------
Key: FTPSERVER-251 URL: https://issues.apache.org/jira/browse/FTPSERVER-251 Project: FtpServer Issue Type: Bug Components: Server Affects Versions: 1.0.0-RC1 Environment: SLES 10 Java6 1.0.0-M4 (with SSL patch for FTPSERVER-241) Reporter: Randy Prager Fix For: 1.0.0 Using a configuration for implicit SSL. & PASV connections Client is Auth TLS + PASV <listeners> <nio-listener name="default" port="XXX" implicit-ssl="false" idle-timeout="60" local-address="XXX"> <ssl> <keystore file="res/xxx.jks" password="password"/> </ssl> <data-connection idle-timeout="60"> <active enabled="false" local-address="XXX" local-port="20"/> <passive ports="XXX-XXX" address="XXXX" external-address="YYYY"/> </data-connection> <blacklist> </blacklist> </nio-listener> </listeners> The LIST command takes approx 10 seconds to complete. It appears that the call to IoUtils.close() in method IODataConnection.transferToClient() is the culprit. I put some trace in the finally block: if (writer != null) { start = System.currentTimeMillis(); writer.flush(); LOG.info("flush in ["+(System.currentTimeMillis()-start)+"] ms."); } start = System.currentTimeMillis(); IoUtils.close(writer); LOG.info("close in ["+(System.currentTimeMillis()-start)+"] ms."); [ INFO] 2008-12-23 12:22:13,892 flush in [0] ms. [ INFO] 2008-12-23 12:22:24,086 close in [10193] ms. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
