Performance Download
Download performance examples using the CLI interface to extract PCAP data to downstream systems.
Please use "stream_dump" to list all captures which can be used with
sudo stream_cat -v <capture name> | ....the output of stream_cat is a standard PCAP via the stdout pipe
NOTE: throughput is heavily dependent on the packet size mix of the capture. Lager packet sizes get a better over all throughput

Manual local file system
Standard pipe to file = 8.8Gbps using linux pipe to file
Manual Rclone local file system
local file system writes ~ 2.4Gbps
Manual NFS remote filesystem (10G Management)
Commands to write data to an NFS share over a 10G management interface ~ 5Gbps throughput
Manual SSH (1G Management)
Stock SSH over 1G management port = 0.48Gbps
Manual SSH (10G Management)
Stock SSH over 10G management port also ~ 0.48 Gbps
Manual SSH arcfour (10G Management)
Using arcfour cipher "-c arcfour" performance is about 1.2Gbps
Manual unencrypted TCP netcat (10G Management)
using netcat on a 10G Management interface over TCP results in near line rate throughput
HTTP on local host
local host HTTP download ~ 6.2Gbps
HTTPS on local host
local host HTTPS download = 3.3Gbps
HTTP on remote 1G
1G link is the bottleneck ~ 0.9Gbps
HTTP on remote 10G (MTU 1500)
10G link HTTP download ~ 4.0 Gbps
HTTP on remote 10G (MTU 9182)
10G HTTP download ~ 4.4Gbps
HTTPS on remote 10G
10G link HTTPS download ~ 1.7Gbps
netcat remote 10G (1500 MTU)
Remove NGINX web server from the setup, throughput only slightly faster 4.8Gbps
S3 HTTP Push rclone (Minio S3 Server 10G)
Push over HTTP (S3 EP is HTTP ) using a 10G interface
