very low requests per second rate with option forceclose

[Stefan Sticht]

Hi,

I need help with my haproxy config. I have been asked to disable keepalive in 
haproxy.
As soon as I use "option forceclose” the requests per second rate mesured with 
apachebench
goes down form like 1000 requests per second to 25 requests per second.

frontend w-test-kon
        bind *:8000
        bind *:8001 ssl crt /etc/ssl/private/wildcard.w.pem
        maxconn 4096000
        default_backend web1

frontend w-test-koff
        option forceclose
        no option http-keep-alive
        bind *:8002
        bind *:8003 ssl crt /etc/ssl/private/wildcard.w.pem
        maxconn 4096000
        default_backend web1

backend web1
        mode http
        balance roundrobin
        http-reuse always
        server web1-ip1 192.168.2.11:80 check source 192.168.2.211
        option httpchk
        maxconn 4096000
        http-response set-header Strict-Transport-Security "max-age=16000000; 
includeSubDomains; preload;"

Without forceclose:

$ ab -v 1 -k -c 10 -n 1000 https://w:8001/test/index.html | grep -e Requests -e 
Complete -e Failed
Complete requests:      1000
Failed requests:        0
Requests per second:    1112.29 [#/sec] (mean)

With foreclose:

$ ab -v 1 -k -c 10 -n 1000 https://w:8003/test/index.html | grep -e Requests -e 
Complete -e Failed
Complete requests:      1000
Failed requests:        0
Requests per second:    25.86 [#/sec] (mean)

Whatever I configure as soon as I disable keepalive I am down to 24-45 requests 
per second.

Anyone an idea what I am doing wrong?

Thanks in advance!

Stefan
