Hi, I try to reduce bandwith use with ssl and compression. I create a test with: 1.
CentOS release 6.6 (Final )x86_64
a.
openssl-1.0.1e-30.el6_6.4.x86_64
b.
kernel-2.6.32-504.1.3.el6.x86_64 2.
PostgreSQL 9.3.5
a.
postgresql93-libs-9.3.5-1PGDG.rhel6.x86_64
b.
postgresql93-contrib-9.3.5-1PGDG.rhel6.x86_64
c.
postgresql93-9.3.5-1PGDG.rhel6.x86_64
d.
postgresql93-server-9.3.5-1PGDG.rhel6.x86_64 I configure a postgresql with SSL (http://www.postgresql.org/docs/9.3/static/ssl-tcp.htm), with self-signed certificate.
All work fine for SSL, but when I try to use the compression I didn’t find any difference monitoring traffic with tcdump. These commands has the same network load (~1.1MB) ·
psql "user=USER password=PASS host=HOST dbname=postgres sslmode=require sslcompression=1" -c "SELECT lpad('', 1024*1024, 'A');" ·
psql "user=USER password=PASS host=HOST dbname=postgres sslmode=require sslcompression=0" -c "SELECT lpad('', 1024*1024, 'A');" ·
psql "user=USER password=PASS host=HOST dbname=postgres sslmode=disable" -c "SELECT lpad('', 1024*1024, 'A');" Best regards, Edoardo Innocenti |
