---------------------------------------
Assignee: David Latorre
> 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
> Assignee: David Latorre
> Fix For: 1.0.0-RC1
>
>
> 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.
