Subject [jira] [Commented] (VFS-546) VFS very slow resolving FTP files
Date Fri, 14 Nov 2014 21:40:34 GMT

    [ 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?

>                 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.
