[jira] [Commented] (VFS-546) VFS very slow resolving FTP files
[ https://issues.apache.org/jira/browse/VFS-546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14212874#comment-14212874 ]
Bernd Eckenfels commented on VFS-546:
-------------------------------------
Can you pinpoint which of the operations is slow? Is it reading the stream (you dont show it in your code) or (what I suspect) the exists() method? Is the directory which contains the file filled with a lot of files?
> VFS very slow resolving FTP files
> ---------------------------------
>
> Key: VFS-546
> URL: https://issues.apache.org/jira/browse/VFS-546
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.0
> Environment: Debian
> Reporter: Sergio Fernández
> Priority: Minor
>
> We have found a performance issue using VFS to access files via FTP. Pushing few MBs takes too long... The code is:
> {code:java}
> FileSystemManager fsmgr = VFS.getManager();
> FileObject f = fsmgr.resolveFile(path);
> if(d.exists()) {
> return f.getContent().getOutputStream();
> }
> {code}
> With the same FTP server both using {{curl}} and a C++ implementation the same file requires few seconds.
> Could be a configuration issue, a usage issue or a bug?
> Thanks in advance.
