<p class=MsoNormal>Hi everybody,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US>I have implemented a multithreaded File
analyser, which compares files within network shares to find duplicates. That
works fine so far, but there is a continuously loss of performance. If I put
for example 400.000 times the same SmbFile into my logic, then everything is
fine, but as soon as I use the listFiles method of SmbFile and I’m going
recursively down that loss of performance is there. Right after the start I’m
able to analyse around 250 files per second, but after 100.000 files I arrive
at 50 files per second and it goes still down. In huge file systems with
several terra bytes this is not so good.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I had used several versions of jCifs so
far, but there was no change. Does anyone know a reason for this behavior or
do I use jCifs in a way it is not intend for?<o:p></o:p></span></p>
