This is quite standard, obviously.

This server at unix.com works exactly the same way, as do most web servers.

You should start with a good web dev tool like the one in your browser which is designed to show you the timing in a water fall manner.

You can easily insert some testing code, like some Javascript, in the mix to help you drill down further.

If your backend server is slow, you need to move to the server and look at the system performance as a whole.

If you have any modern day, decent, back-end server, the bottleneck is often in the page rendering on the web site (too many big files, large javascript libs, etc.)

There is not one single tool which will do the entire process from user at the browser to the database.

You must first isolate the problem, normally with a web dev tool in a browser, and then drill down.

NAME
git-web--browse - Git helper script to launch a web browser SYNOPSIS
git web--browse [OPTIONS] URL/FILE ... DESCRIPTION
This script tries, as much as possible, to display the URLs and FILEs that are passed as arguments, as HTML pages in new tabs on an already opened web browser. The following browsers (or commands) are currently supported: o firefox (this is the default under X Window when not using KDE) o iceweasel o seamonkey o iceape o chromium (also supported as chromium-browser) o google-chrome (also supported as chrome) o konqueror (this is the default under KDE, see Note about konqueror below) o opera o w3m (this is the default outside graphical environments) o elinks o links o lynx o dillo o open (this is the default under Mac OS X GUI) o start (this is the default under MinGW) o cygstart (this is the default under Cygwin) o xdg-open Custom commands may also be specified. OPTIONS
-b <browser>, --browser=<browser> Use the specified browser. It must be in the list of supported browsers. -t <browser>, --tool=<browser> Same as above. -c <conf.var>, --config=<conf.var> CONF.VAR is looked up in the Git config files. If it's set, then its value specifies the browser that should be used. CONFIGURATION VARIABLES
CONF.VAR (from -c option) and web.browser The web browser can be specified using a configuration variable passed with the -c (or --config) command-line option, or the web.browser configuration variable if the former is not used. browser.<tool>.path You can explicitly provide a full path to your preferred browser by setting the configuration variable browser.<tool>.path. For example, you can configure the absolute path to firefox by setting browser.firefox.path. Otherwise, git web--browse assumes the tool is available in PATH. browser.<tool>.cmd When the browser, specified by options or configuration variables, is not among the supported ones, then the corresponding browser.<tool>.cmd configuration variable will be looked up. If this variable exists then git web--browse will treat the specified tool as a custom command and will use a shell eval to run the command with the URLs passed as arguments. NOTE ABOUT KONQUEROR
When konqueror is specified by a command-line option or a configuration variable, we launch kfmclient to try to open the HTML man page on an already opened konqueror in a new tab if possible. For consistency, we also try such a trick if browser.konqueror.path is set to something like A_PATH_TO/konqueror. That means we will try to launch A_PATH_TO/kfmclient instead. If you really want to use konqueror, then you can use something like the following: [web] browser = konq [browser "konq"] cmd = A_PATH_TO/konqueror Note about git-config --global Note that these configuration variables should probably be set using the --global flag, for example like this: $ git config --global web.browser firefox as they are probably more user specific than repository specific. See git-config(1) for more information about this. GIT
