The fs-cifs filesystem manager is very slow.

Hi,
Is there any way to speed up transmission between NT server and QNX machine
running fs-cifs filesystem manager.

Hardware configuration:
Server: Dell dual processor server with 100Mbit network card.

QNX machine: 500MHz Pentium with 100Mbit network card running QNX 6.0.

If I boot my “QNX” machine with Windows to copy 24MB file from the server
takes 8 sec. But it takes about 10 minutes to copy the same file over
fs-cifs manager. ( I was using copy command and cp under QNX)

I am sure that a network card works with 100Mbits speed.
io-net runs full tcpip protocol.

Gurus please advice where is my bottleneck.

Does a non MS server show the same symptoms? If not, this
is probably an issue we’ve seen before which is worked
around in the 6.2 version of fs-cifs.

Well … and it works also only a limited time before it locks up.

Hardware configuration:
Server: Dell dual processor server with 100Mbit network card.

QNX machine: 500MHz Pentium with 100Mbit network card running QNX 6.0.

I don’t believe this is not only a fs-cifs problem.
When I try to copy a complete directory tree from one QNX6 machine to an
other … it
takes 30 minutes. A copy of the equivilent tar ball takes seconds :slight_smile:

I am sure that a network card works with 100Mbits speed.

That’s a good question …

I had the same problem and Weijie Zhang (ask him) gave me a fs-cifs version for
which the speed is very close to NT-NT exchanges.

This is the results:

To copy a 505,866,630 bytes file:

With the new fs-cifs (QRTP to NT): 10 mns.
With the new fs-cifs (QRTP to HPUX running samba 1.9.18p4): 10 mns.
With Samba 2.2.0 (NT from QRTP): 9 mns.
With Samba 2.2.1a (NT from QRTP): 9 mns.

With ftp (QRTP to NT): 8 mns.

regards,
Alain.

Hi Alain,
Thanks for info. Could you please provide Mr Zhang e-mail address or any
contact information.
