I'm looking to improve my samba writing performance but I Fear I've
either tweaked something wrong or not tweaked it enough and as such
I'm looking for any and all criticism that might improve my situation.
Admittedly I'm running somewhat of a Frankenstein system - older P3 /w
too many pci cards that sadly in some ways have to share the same IRQ
(the Compaq BIOS in manual IRQ assignment is not very flexible). I
have however gone out of my way to disable whatever I am not using -
- eg sound, PATA, onboard usb 1.1, etc. And yes that is a CMD Silicon
Image 3512 PCI add-in card /w 1TB western digital SATA drive on IRQ 14
-- it was fun to watch the machine boot from the SATA DVDRW.
"Out of the box" was performance just short of abysmal. I can't
currently remember the exact output numbers but doing a windows to
samba copy worked at about 2MB/s (watching systat vmstat as it writes
to the HD).
By adding the following to OpenBSD:
--------------
net.inet.ip.ifq.maxlen=768 # Maximum input queue (256*number of interfaces)
net.inet.icmp.errppslimit=1000 # Maximum outgoing ICMP error messages per sec
net.inet.ip.ttl=254 # TTL = "min-ttl" in scrub rule in pf.conf
net.inet.tcp.ackonpush=1 # acks for packets with the push bit no delay
net.inet.tcp.ecn=1 # Explicit Congestion Notification enabled
net.inet.tcp.mssdflt=1452 # maximum segment size (1452 from scrub pf.conf)
net.inet.tcp.rfc1323=1 # RFC1323 TCP window scaling
net.inet.tcp.recvspace=262144 # Increase TCP "recieve" windows size to increas
e performance
net.inet.tcp.sendspace=262144 # Increase TCP "send" windows size to increase p
erformance
net.inet.tcp.sack=1 # enable TCP Selective ACK (SACK) Packet Recover
y
net.inet.udp.recvspace=262144 # Increase UDP "recieve" windows size to increas
e performance
net.inet.udp.sendspace=262144 # Increase UDP "send" windows size to increase p
erformance
--------------
and the following performance option in smb.conf
--------------
socket options = IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
sync always = no
read raw = no
write raw = no
--------------
I managed to get my internal network interface (re0) to 4000
interupts/sec and a wd0 write speed between 4MB and 12MB per second.
Again any help anyone can give me that might improve my overall write
speed would be greatly appriciated.
incase you're wondering the system is for a home network firewall /w
wireless support. dmesg follows:
