Minimum server-side performance impactWhen cache files are created Web Optimizer wastes about 1-5 ms to parse and refresh outputted HTML document (with default settings, correct one-string mode for HTML is the very expensive procedure and can take 50-100 ms additionally). Acceleration statisticsAfter series of tests on default CMS installations Web Optimizer showed average page loading speed of 250% of normal (and up to 500% in several cases). To be accurate, average acceleration is 2.5 times (+21 in YSlow grade, -34% in size, -43% in objects). Table below shows how greater website speed increases after Web Optimizer installation. Note that all CMS are tested in one particular environment with ~100KB/s broadband and Firefox 3.5 browser. Websites are loaded several times to fill proxy cache and to get necessary statistics. Local cache is emptied before each load. | CMS | YSlow | Load time (s) | Size (KB) | Objects | | | Before | After | Before | After | Before | After | Before | After | | Bitrix 8.5.1 | 61 | 92 | 4.37 | 2.21 | 239 | 194 | 53 | 28 | | CMS Made Simple | 74 | 96 | 0.483 | 0.375 | 49 | 35 | 15 | 5 | | cogear 1.0 | 76 | 91 | 5.11 | 1.57 | 447 | 129 | 11 | 9 | | DataLife Engine 8.0 | 65 | 91 | 4.48 | 1.29 | 147 | 120 | 43 | 16 | | Drupal 6.10 | 72 | 94 | 4.8 | 1.34 | 102 | 99 | 32 | 8 | | Etomite 1.1 | 89 | 96 | 0.874 | 0.477 | 19 | 14 | 7 | 6 | | ExpressionEngine 1.6.8 | 96 | 99 | 0.584 | 0.257 | 10 | 4 | 3 | 2 | | IPB 2.3.6 | 67 | 89 | 4.38 | 1.81 | 124 | 52 | 27 | 25 | | Joomla! 1.0.15 | 78 | 92 | 0.996 | 0.521 | 47 | 39 | 18 | 13 | | Joomla! 1.5.10 | 64 | 94 | 4.38 | 1.57 | 139 | 73 | 42 | 9 | | Joostina 1.2 | 63 | 91 | 8.07 | 3.77 | 426 | 333 | 45 | 17 | | Livestreet 0.3.1 | 51 | 96 | 10.87 | 1.97 | 298 | 111 | 48 | 5 | | MaxDev Pro 1.082 | 75 | 93 | 2.4 | 0.871 | 51 | 36 | 27 | 21 | | MaxSite 0.3.1 | 71 | 97 | 2.73 | 1.12 | 152 | 90 | 15 | 5 | | MODx 0.9.6.3 | 69 | 97 | 2.73 | 0.842 | 109 | 51 | 18 | 4 | | OpenSlaed 1.2 | 77 | 83 | 5.51 | 3.37 | 257 | 250 | 92 | 72 | | osCommerce 2.2 | 77 | 93 | 3.05 | 1.24 | 72 | 65 | 31 | 31 | | PHP-Nuke 8.0 * | 72 | 91 | 2.785 | 1.272 | 181 | 91 | 19 | 19 | | phpBB 3.0.4 | 72 | 95 | 0.651 | 0.305 | 85 | 71 | 19 | 7 | | SMF 1.1.8 ** | 61 | 91 | 2.68 | 1.72 | 183 | 132 | 63 | 25 | | Textpattern 4.0.8 | 92 | 97 | 1.26 | 0.823 | 8 | 5 | 4 | 4 | | UMI.CMS 2.7 | 58 | 93 | 4.52 | 2.89 | 269 | 177 | 59 | 10 | | vBulletin 3.8.3 | 70 | 92 | 3.33 | 1.81 | 124 | 67 | 20 | 14 | | Website Baker 2.6 | 77 | 95 | 1.51 | 0.47 | 17 | 12 | 10 | 8 | | Wordpress 2.7.1 | 72 | 95 | 4.58 | 2.08 | 133 | 125 | 31 | 6 | | Xaraya 1.1.5 | 81 | 97 | 1.79 | 0.78 | 35 | 16 | 8 | 4 | | XOOPS 2.3.3 | 72 | 95 | 3.22 | 1.53 | 65 | 50 | 21 | 8 |
