Hello,
After the last patch I submitted with regarding to /etc/services,
I was asked if I could see if I could do something about the speed
of it. Personally I don't worry too much about it, my programs only
access getservbyname() only once per program :-)
I did some tests with it, and at this

I think there is cached(8) daemon in -current that does exactly this,
and more. Dunno if it will get in -stable.
I was pointed to that by grog@, but I never heard

Hi,
As far as I remember this topic has been already discussed.
There are basically 2 ways of speeding up /etc/services queries:
1. To use /etc/passwd-/pwd.db scheme - i.e. using BDB as the main data
storage and allowing user to update it from /etc/services file by request.
2. Use the

This is not terribly surprising rx is currently a more expensive
operation than tx on FreeBSD. My testing on 10GigE indicates that
there is ample room for improvement.

Hello,
First of, I am not sure if this is the correct mailing list for my
queries. Please do let me know if this isn't the right one.
I am interested in tracking send/recv queues at the transport layer for
TCP and SCTP.
- Is netstat the only way to achieve this tracking?

Hi,
I had a crash on a VPN router today running FAST_IPSEC. The message on
the console was something along the lines of panic sleeping on a non
sleepable lock. The system was a 6.2 RELEASE system running AMD64.
Here is a back trace. Should I open a PR about this?

One more thing to remember is to raise the socket size on the linux
sender. I found that I got very poor tx performance on linux running
netperf without making the socket buffers fairy large.

Hi Jack -
I believe I've fixed the sun4v breakage caused by the interrupt filter
changes but it appears that em still isn't working. Does Intel test at
all on big endian hardware? If not, what do you do to avoid breaking
e1000 on Linux?
Thanks.

Ours did too prior to the recent import :D
