[Samba] Slow response & excessive CPU utilization with Foxpro
I have a samba server (2.2.7) installed. Server is RedHat 7.1. It is installed from an RedHat RPM samba-2.2.7-1.7.3.i386.rpm. Clients are all XP Pro. Everything works, but when a database program (based on MS Visual FoxPro) runs its databases from there (the samba server), the server CPU utilization of smbd goes to 98% and stays there until the data transfer is done. The data transfer also is extremely slow. Only about 0.5% of the bandwith of 10baseT gets used according to XP Pro task manager on the client. I have tried disabling oplocks, level 2 oplocks and kernel oplocks in the global level and also in the share level. I also tried adjusting send and receive buffers (default 8192) to 4096. TCP_NODELAY is set, too. So far nothing has worked. Any ideas on what to try next? Thanks Jon
