Subject RE: Slow Response Time Using Proxies
Date Fri, 19 Jul 2002 08:24:54 GMT
I have tried turning hostname lookups off, and it does not make a
difference. I have a name server running on my local network so lookups
are very fast. Additionally, I see good performance for pages that are
not served through the proxy.

It may be that the cause lies in the configuration of my machine or
Linux rather than in Apache itself, but there is nothing obvious that I
can think of. The server is a dual Pentium III Zeon system with 2GB of
ram, and sees very little traffic at the moment. The Linux installation
is standard as well.

I appreciate your suggestion, and welcome any other advice. I am really
stuck on this one.

Regards,

Michael Schonberg

    You don't have "HostNameLookup on", do you?
    It can slow things if you have a slow DNS...

Subject: Slow Response Time Using Proxies


I am using Apache 2.0.39 on Redhat Linux 7.3 with the following proxy to
foreword requests to Jetty: 
        ProxyPass /cart/ http://localhost:8080/cart/ 
        ProxyPassReverse / http://localhost:8080/ 
When a page is accessed through this proxy it takes over 5 seconds to
load; however, the same pages loads instantaneously if I access it
directly through "https://localhost:8080/cart/...". I built Apache with
the following options: --enable-usertrack --enable-ssl --enable-proxy
--enable-rewrite --with-mpn=worker. I am also using URL rewriting;
however, I have tried disabling rewriting, as well as disabling SSL with
no luck. Thanks in advanced for your assistance. I have included my
httpd.conf file at the end of this message.

# 
# Based upon the NCSA server configuration files originally by Rob
McCool. 
# 
# This is the main Apache server configuration file.  It contains the 
# configuration directives that give the server its instructions. 
# See <URL:http://httpd.apache.org/docs-2.0/> for detailed information
about 
# the directives. 
# 
# Do NOT simply read the instructions in here without understanding 
# what they do.  They're here only as hints or reminders.  If you are
unsure 
# consult the online docs. You have been warned.  
# 
# The configuration directives are grouped into three basic sections: 
#  1. Directives that control the operation of the Apache server process
as a 
#     whole (the 'global environment'). 
#  2. Directives that define the parameters of the 'main' or 'default'
server, 
#     which responds to requests that aren't handled by a virtual host. 
#     These directives also provide default values for the settings 
#     of all virtual hosts. 
#  3. Settings for virtual hosts, which allow Web requests to be sent to

#     different IP addresses or hostnames and have them handled by the 
#     same Apache server process. 
# 
# Configuration and logfile names: If the filenames you specify for many

# of the server's control files begin with "/" (or "drive:/" for Win32),
the 
# server will use that explicit path.  If the filenames do *not* begin 
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log" 
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the

# server as "/usr/local/apache2/logs/foo.log". 
# 
### Section 1: Global Environment 
# 
# The directives in this section affect the overall operation of Apache,

# such as the number of concurrent requests it can handle or where it 
# can find its configuration files. 
# 
# 
# ServerRoot: The top of the directory tree under which the server's 
# configuration, error, and log files are kept. 
# 
# NOTE!  If you intend to place this on an NFS (or otherwise network) 
# mounted filesystem then please read the LockFile documentation 
# (available at
<URL:http://httpd.apache.org/docs-2.0/mod/core.html#lockfile>); 
# you will save yourself a lot of trouble. 
# 
# Do NOT add a slash at the end of the directory path.

# scoreboard file. The scoreboard file MUST BE STORED ON A LOCAL DISK.

# DefaultLanguage and AddLanguage allows you to specify the language of 
# a document. You can then use content negotiation to give a browser a 
# file in a language the user can understand. 
# 
# Specify a default language. This means that all data 
# going out without a specific language tag (see below) will 
# be marked with this one. You probably do NOT want to set 
# this unless you are sure it is correct for all cases. 
# 
# * It is generally better to not mark a page as 
# * being a certain language than marking it with the wrong 
# * language! 
# 
# DefaultLanguage nl 
# 
# Note 1: The suffix does not have to be the same as the language 
# keyword --- those with documents in Polish (whose net-standard 
# language code is pl) may wish to use "AddLanguage pl .po" to 
# avoid the ambiguity with the common suffix for perl scripts. 
# 
# Note 2: The example entries below illustrate that in some cases 
# the two character 'Language' abbreviation is not identical to 
# the two character 'Country' code for its country, 
# E.g. 'Danmark/dk' versus 'Danish/da'. 
# 
# Note 3: In the case of 'ltz' we violate the RFC by using a three char 
# specifier. There is 'work in progress' to fix this and get

# Specify a default charset for all pages sent out. This is

#  to be distributed in multiple languages.)

# Customizable error responses come in three flavors:

# 
# We use Alias to redirect any /error/HTTP_<error>.html.var response to 
# our collection of by-error message multi-language collections.  We use

# includes to substitute the appropriate text. 
# 
# You can modify the messages' appearance without changing any of the 
# default HTTP_<error>.html.var files by adding the line; 
# 
#   Alias /error/include/ "/your/include/path/" 
# 
# which allows you to create your own set of files by starting with the 
# /usr/local/apache2/error/include/ files and 
# copying them to /your/include/path/, even on a per-VirtualHost basis.

# Section 3: Virtual Hosts 
# 
# VirtualHost: If you want to maintain multiple domains/hostnames on
your 
# machine you can setup VirtualHost containers for them. Most
configurations 
# use only name-based virtual hosts so the server doesn't need to worry
about 
# IP addresses. This is indicated by the asterisks in the directives
below. 
# 
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs-2.0/vhosts/> 
# for further details before you try to setup virtual hosts. 
# 
# You may use the command line option '-S' to verify your virtual host 
# configuration. 
# 
# Use name-based virtual hosting. 
# 
#NameVirtualHost * 
# 
# VirtualHost example: 
# Almost any Apache directive may go into a VirtualHost container. 
# The first VirtualHost section is used for requests without a known 
# server name. 
# 
#<VirtualHost *> 
#    ServerAdmin webmaster@dummy-host.example.com 
#    DocumentRoot /www/docs/dummy-host.example.com 
#    ServerName dummy-host.example.com 
#    ErrorLog logs/dummy-host.example.com-error_log 
#    CustomLog logs/dummy-host.example.com-access_log common 
#</VirtualHost>
