RE: [Samba] Samba very, VERY slow ...
-Original Message- From: John H Terpstra [mailto:[EMAIL PROTECTED] Eric, Suggest you replace the ethernet card and/or the network cable. Sounds like a hardware issue. Mismatched duplex settings (full vs. half) can also do this. Not all hubs/switches auto-detect the ethernet card's setting properly. Classic symptoms of a duplex mismatch are that pings and small transfers to/from the machine work fine, but large transfers (with FTP, samba, or anything else) bog down badly. -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba

Not all hubs/switches auto-detect the ethernet card's setting properly. [...] Thanks for your help ! I've found a solution to my problem : I've added the option : socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=8192 SO_SNDBUF=8192 instead of only : socket options = TCP_NODELAY Now, the clients open the appli under 4 seconds !!! (instead of 40 before!). And moreover : i think they open under 4 seconds because they are slow and they have to analyse the data sended by samba. Samba should bring them the data under a much more short delay !!! -- oO--Oo Eric MAISONOBE [EMAIL PROTECTED] oO--Oo -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba

Re: [Samba] Samba very, VERY slow ...
Hi, We had similar, very baffleing symptoms with MYOB Premier opening and accessing it's datafiles. operations on the file would take between 40 and 45 seconds. It turned out that it was a printer monitor program running on the clients causing the problems. Looking at the logs, we saw them coming through with pauses of about 1 second between groups. Stopping the monitor software resulted in the networks access at normal (quick) speed. Restarting the program caused the speed to slow down again. The printer was a cannon lbp810 and the relevant task was something like CAPON (not sure on spelling). The monitor software displayed a printing now dialog on the client when they printed. We only discovered this by starting with a clean install of windows and trying the app at every step of the installation of other software process. (had to do this many times) Moral of the story, check everything (other software included)! Hope it is not something like this (it will be painful to find) Joe Healy On Fri, Oct 17, 2003 at 10:59:35AM +0200, Eric Maisonobe wrote: Hello !

Re: [Samba] Samba very, VERY slow ...
Joseph, I'd like to thank you for your diligent attention to detail and particularly for reporting your findings. This is a real gem of a contribution that may save someone else many days of frustration. Cheers, John T.

RE: [Samba] Samba very, VERY slow ...
All goes right, but the systeme (P3-800Mhz-256Mo RAM for 8 users) is very, VERY slow (about 40 second to open the application). Stab in the dark - Could it be because of network bottleneck?? I'm running on a 10MB/s network, it's also slow to load files.. but maybe not as slow as 40seconds. How big are the files? Maybe you can perform a rough estimate of the network transfer speed. (not sure how though) :( Cheers, .^.
