Sissejuhatus
Selleks, et Samba jõudlust parandada, tuleb konfigureerida SOCKET OPTIONS
Socket options
TCP_NODELAY - Seda kasutatake telneti ühenduste puhul, et saavutada lühikest kosteaega (kui kiiresti saab päringule vastuse).
Have the server send as many packets as necessary to keep delay low. This is used on telnet connections to give good response time, and is used - somewhat counter-intuitively - to get good speed even when doing small requests or when acknowledgments are delayed (as seems to occur with Microsoft TCP/IP). This is worth a 30-50 percent speedup by itself.
IPTOS_LOWDELAY - This is another option that trades off throughput for lower delay, but which affects routers and other systems, not the server. All the IPTOS options are new; they're not supported by all operating systems and routers. If they are supported, set IPTOS_LOWDELAY whenever you set TCP_NODELAY.
SO_SNDBUF and SO_RCVBUF - send ja receive buffreid saab seadistada suuremaks, kui on operatsioonisüsteemil. Sellega kasvab kiirus märgatavalt.
SO_KEEPALIVE - määrab, kui pika aja jooksul kontrollitakse, kas klient on veel serveriga ühenduses.
This initiates a periodic (four-hour) check to see if the client has disappeared. Expired connections are addressed somewhat better with Samba's keepalive and dead time options. All three eventually arrange to close dead connections, returning unused memory and process-table entries to the operating system.
