cvs commit: src/sys/sys buf.h

[Leroy van Logchem]

Hi Poul,

These questions might not be related but I'll ask anyway.
(I'am not very technical nor expect on kernel design so bare with me please)

sysctl reports:
--------------
kern.ipc.nmbclusters: 3072
BIO buffer            214   428K    668K   101107  2048
sysctl -a | grep -C3 "mbuf" | more

Side question: Is the a case convention for the info in sysctl -a?

sysctl -a | grep -C3 -i "mbuf" | more
MbufClust:            2048,     3072,    256,      6,      256
Mbuf:                 256,         0,    257,    133,  3562331

Q: Which of these will be dynamic by default in RELENG_5_3?

Using 5.2.1 we had to tune several kernel params using trail'n'error during
production time.

Q: Will nmbclusters, kmem_size and kmem_scale avoid service-outages in 
the future?
(bufferspace unavailable, out of kmem etc.)


Cheers,
Leroy
