se the commands below to provide key information from your environment:
You do NOT have to include this information if this is a FEATURE REQUEST

What version of frp are you using (./frpc -v or ./frps -v)?
0.29.0

What operating system and processor architecture are you using (go env)?

GOTOOLDIR="/usr/lib/go-1.10/pkg/tool/linux_amd64"
GCCGO="gccgo"
CC="gcc"
CXX="g++"
CGO_ENABLED="1"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"

GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build406901856=/tmp/go-build -gno-record-gcc-switches"

Configures you used:

// frpc.ini
server_addr = my public server ip
server_port = 7000

[ssh]
type = tcp
local_ip = 127.0.0.1
local_port = 22
remote_port = 2224

[plex]
type = tcp
local_ip = 127.0.0.1
local_port = 32400
remote_port = 30300

[range:mosh]
type = udp
local_ip = 127.0.0.1
local_port = 60000-60010
remote_port = 60000-60010

Steps to reproduce the issue:

run rsync ubuntu.iso -v --progress user@frps-server-ip: from my office

frps-server-ip is a ssh host alias of my public server + port 2224 via .ssh/config

Describe the results you received:
The max bandwidth reached was about only 5MiB/s which was 20MiB/s when through sshd gateway reversed tunnel.

Describe the results you expected:
similar or faster than sshd reversed tunnel which has ssh encryption decryption overhead.

Additional information you deem important (e.g. issue happens only occasionally):

Can you point out what caused this issue (optional)
