DO NOT REPLY [Bug 50942] New: Apache 2.2.16 forward proxy is 5x
times slower than apache2.2.4
https://issues.apache.org/bugzilla/show_bug.cgi?id=50942
Summary: Apache 2.2.16 forward proxy is 5x times slower than
apache2.2.4
Product: Apache httpd-2
Version: 2.2.6
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: mod_proxy
AssignedTo: bugs@httpd.apache.org
ReportedBy: murthy_bodapati@rediffmail.com
We are using apache as a forward proxy and recently we migrated from
apache2.2.4 to apache2.2.16.
We observed that apache2.2.16 is taking almost an extra 5x time to fetch the
page when compared to apache2.2.4
Steps to reproduce:
Configuring Apache
1. Configure apache by the below command
./configure --prefix=/usr/local/apache --enable-mods-shared="proxy_connect
proxy_ftp proxy_http proxy status rewrite deflate" --with-mpm=worker
--with-included-apr
make install
2. Set the parameter "ProxyRequests = On" and start the apache.
3. Check the time taken to server the page by executing the below command
curl -o /dev/null -s -w %{time_total} -x <ServerName>:<Port> www.youtube.com
We see this dip in performance in apache2.2.6 also.

care to try this change, to back out one of the proxy fixes between 2.2.4 and
2.2.6?

We use apache as a forward proxy and want to migrate from 2.2.4 to 2.2.16. But
could not take the migration step as 2.2.16 is very very slow in comparison to
2.2.4.

Hi I applied it, but still it is taking time.
In the error log, I see it spends 2 seconds for sending itself.

[Thu Mar 17 23:18:14 2011] [debug] mod_proxy_http.c(1840): proxy: end body send
