| 1 Gross Dynamic Footprint Reports | |

| 5 This is a short primer on how to run the ``gross dynamic footprint'' | |
| 6 reports. | |
| 7 | |
| 8 Win32 | |
| 9 ----- | |
| 10 | |
| 11 I've tried this on Win2K. Should work on NT, probably not 98. | |
| 12 | |
| 13 1. Configure your machine with a ``standard'' mozilla build | |
| 14 environment, as described at: | |
| 15 | |
| 16 http://www.mozilla.org/build/win32.html | |
| 17 | |
| 18 Specifically, you'll need the Cygnus tools (GNU make, awk, sed), which | |
| 19 can be downloaded from: | |
| 20 | |
| 21 http://sourceware.cygnus.com/cygwin/download.html | |
| 22 | |
| 23 2. Install the Win32 version of GNUplot, avaialable from: | |
| 24 | |
| 25 ftp://ftp.dartmouth.edu/pub/gnuplot/gnuplot3.7cyg.zip | |
| 26 | |
| 27 3. Configure a web server with the ``buster.cgi'' CGI script contained | |
| 28 in this directory. | |
| 29 | |
| 30 4. Pull and build a ``release'' build. Besides the normal Win32 flags | |
| 31 described on the Win32 build instructions, be sure that you've set the | |
| 32 following: | |
| 33 | |
| 34 set BUILD_OPT=1 | |
| 35 set MOZ_DEBUG= | |
| 36 | |
| 37 That is, MOZ_DEBUG should be unset. | |
| 38 | |
| 39 5. To collect data and build the dynamic footprint graph, type the | |
| 40 following command from the mozilla/tools/footprint directory: | |
| 41 | |
| 42 make --unix -fwin32-gdf.mk \ | |
| 43 BUSTER_URL="http://myserver/cgi-bin/buster.cgi?refresh=10" | |
| 44 | |
| 45 (Replace ``myserver'' with the name of the webserver where you | |
| 46 installed ``buster.cgi'' in step 3, above.) | |
| 47 | |
| 48 This should: | |
| 49 | |
| 50 - Build ``wm.exe'', which will spy on memory usage. | |
| 51 - Run the winEmbed program over the top 100 URLs (from top100.txt) | |
| 52 to generate a file called ``winEmbed.dat'' | |
| 53 - Run mozilla over the top 100 URLs to generate a file called | |
| 54 ``mozilla.dat'' | |
| 55 - Use gnuplot to create a PNG image file called win32-gdf.png | |
| 56 | |
| 57 Linux | |
| 58 ----- | |
| 59 | |
| 60 1. Configure your machine with a ``standard'' mozilla build | |
| 61 environment, as described at: | |
| 62 | |
| 63 http://www.mozilla.org/build/unix.html | |
| 64 | |
| 65 2. Install GNUplot, which is available as an RPM on RedHat-6.2 CDs | |
| 66 (probably others, as well). | |
| 67 | |
| 68 3. Configure a web server with the ``buster.cgi'' CGI script contained | |
| 69 in this directory. | |
| 70 | |
| 71 4. Pull and build a ``release build''. Here are the settings you | |
| 72 should use in your .mozconfig file: | |
| 73 | |
| 74 ac_add_options --enable-optimize | |
| 75 ac_add_options --disable-debug | |
| 76 ac_add_options --enable-strip-libs | |
| 77 | |
| 78 5. To collect data and build the dynamic footprint graph, type the | |
| 79 following command from the mozilla/tools/footprint directory: | |
| 80 | |
| 81 make -flinux-gdf.mk \ | |
| 82 BUSTER_URL="http://myserver/cgi-bin/buster.cgi?refresh=10" | |
| 83 | |
| 84 (Replace ``myserver'' with the name of the webserver where you | |
| 85 installed ``buster.cgi'' in step 3, above.) | |
| 86 | |
| 87 Details, details, details | |
| 88 ------------------------- | |
| 89 | |
| 90 1. When running these tests, you'll probably want to use predictable | |
| 91 cache settings. You can modify $(DIST)/bin/defaults/pref/all.js to | |
| 92 tweak settings that will be used by [win|gtk]Embed (these programs | |
| 93 ignore profile-specific settings AFAIK). For example, I've used these | |
| 94 to try to cull out cache usage altogether: | |
| 95 | |
| 96 pref("browser.cache.disk_cache_size", 0); | |
| 97 pref("browser.cache.enable", false); | |
| 98 pref("browser.cache.disk.enable", false); | |
| 99 pref("browser.cache.memory_cache_size", 0); | |
| 100 pref("browser.cache.disk_cache_ssl", false); | |
| 101 | |
| 102 I think the image cache has a pref that you can use to shut it off as | |
| 103 well. Haven't found it yet. | |
| 104 | |
| 105 2. If you collect data using Mozilla (as Win32 will do, by default), I | |
| 106 recommend using a clean profile for consistency's sake. Otherwise, | |
| 107 results will vary based on random stuff like how big your bookmarks | |
| 108 are, how big your global history is, whether or not you've started | |
| 109 mail, etc. | |
| 110 | |
| 111 3. I removed the ``plugin downloader plugin'' libnullplugin.so, as | |
| 112 well as all other plugins, from $(DIST)/bin/plugins so that no plugins | |
| 113 would be loaded. |
