Redis Performance Issue

[Luo-Liang]

Hi! I'm further testing f-stack, but I have trouble getting good result from Redis.
I use 1 Machine to run f-stack/app/redis and original redis, and another machine a redis-benchmark that just keep issuing GET commands.

Here is the result:
f-stack redis latency: 200us vs stock redis latency: 112us.

The client is the same, and does not use dpdk.

F-stack is 2x slower than stock redis. I am wondering if I set anything wrong. The command I used:

sudo ./redis-server --conf config.ini --proc-type=primary --proc-id=0 ../redis.conf,

and config.ini looks like this:

[dpdk]
## Hexadecimal bitmask of cores to run on.
lcore_mask=0x7
channel=4
promiscuous=1
numa_on=1
## TCP segment offload, default: disabled.
tso=0
## HW vlan strip, default: enabled.
vlan_strip=1

# enabled port list
#
# EBNF grammar:
#
#    exp      ::= num_list {"," num_list}
#    num_list ::= <num> | <range>
#    range    ::= <num>"-"<num>
#    num      ::= '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9'
#
# examples
#    0-3       ports 0, 1,2,3 are enabled
#    1-3,4,7   ports 1,2,3,4,7 are enabled
port_list=0

## Port config section
## Correspond to dpdk.port_list's index: port0, port1...
[port0]
addr=172.31.9.164
netmask=255.255.240.0
broadcast=172.31.15.255
gateway=172.31.0.1

## lcore list used to handle this port
## the format is same as port_list
# lcore_list= 0

## Packet capture path, this will hurt performance
#pcap=./a.pcap

## Kni config: if enabled and method=reject,
## all packets that do not belong to the following tcp_port and udp_port
## will transmit to kernel; if method=accept, all packets that belong to
## the following tcp_port and udp_port will transmit to kernel.
#[kni]
#enable=1
#method=reject
## The format is same as port_list
#tcp_port=80,443
#udp_port=53

Any advice on this? Thanks!
