[jcifs] Performance Issue with jcifs and NetApp

[TransConnect]

Hallo,

we are using jcifs (1.3.17) to list a folder on a NetApp filer (OnTap
8.1.P1) under Linux (64Bit).
All works without any error but the listing runs over 90 seconds to get the
list of approx. 100 file names.
For testing purposes we used the jcifs example ListFiles adding
NtlmPasswordAuthentication using domain name with the same results.

Mounting that share on the same machine works as fast as expected.

We have tried to set the following properties:

jcifs.smb.lmCompatibility=2
jcifs.smb.client.useExtendedSecurity=false
jcifs.resolveOrder=LMHOSTS,WINS,DNS

but there is no difference in response time. If we try to read a file the
operation will run over 13 minutes.

Are there any other options to try to increase the performance? Are there
known problems accessing NetApp in current jcifs release?

Thanks for Your help.
Torsten
