Power How many packets can be written into Kernel sockets per second?
Hi,

Its been a long time since i programmed a multithreaded application that can do Tx and Rx of datagrams over unix sockets.

I well remember that though the threads were efficiently designed to be independent of each other, and was writing to different sockets, there was a limitation , which i remember that only 3000 approximate datagrams/packets can be sent/received between the host application and the kernel - which i came to know from some forums, and infact, our timers used to expire due to non-reception of approx >3000 packets if it was configured - reason being the kernel to host transfer of the packets were slow.

Before i could attempt figuring out that again, wanted to ask if anyone knows a theoretical limitation seen by the linux kernels?
In other terms, what is the max data transfer rate between the Kernel space and user space through the various IPC mechanisms?

If i don't get to know that, i may end up doing an assumption.

dbus-cleanup-sockets(1) 				      General Commands Manual					   dbus-cleanup-sockets(1)

NAME

       dbus-cleanup-sockets - clean up leftover sockets in a directory

SYNOPSIS

       dbus-cleanup-sockets [DIRECTORY]

DESCRIPTION

       The dbus-cleanup-sockets command cleans up unused D-Bus connection sockets. See http://www.freedesktop.org/software/dbus/ for more informa-
       tion about the big picture.

       If given no arguments, dbus-cleanup-sockets cleans up sockets in the standard default socket directory for the per-user-login-session  mes-
       sage bus; this is usually /tmp.	Optionally, you can pass a different directory on the command line.

       On  Linux, this program is essentially useless, because D-Bus defaults to using "abstract sockets" that exist only in memory and don't have
       a corresponding file in /tmp.

       On most other flavors of UNIX, it's possible for the socket files to leak when programs using D-Bus  exit  abnormally  or  without  closing
       their  D-Bus connections. Thus, it might be interesting to run dbus-cleanup-sockets in a cron job to mop up any leaked sockets.	Or you can
       just ignore the leaked sockets, they aren't really hurting anything, other than cluttering the output of "ls /tmp"
