Thanks Amos. We are already on a Production, cant really think about upgrading without knowing the impact and benefits, for now. On the other hand, i picked up the "TCP_HIT" from my production box that is a lot used, seem to have many there. 1368107093 000000 10.56.9.27 TCP_HIT/200 738 GET http://wikid.domain.com/wikid/skins/common/images/Arr_.png - HIER_NONE/- image/png 1368110324 000001 10.56.9.27 TCP_HIT/200 5143 GET http://wikid.domain.com/wikid/skins/common/images/spinner.gif - HIER_NONE/- image/gif 1368110509 000001 10.56.9.27 TCP_HIT/200 2169 GET http://wikid.domain.com/wikid/skins/monobook/IE60Fixes.css? - HIER_NONE/- text/css 1368110510 000001 10.56.9.27 TCP_HIT/200 557 GET http://wikid.domain.com/wikid/skins/monobook/external.png - HIER_NONE/- image/png 1368113664 000001 10.56.9.27 TCP_HIT/200 897 GET http://wikid.eng.domain.com/wikid/skins/common/images/button_image.png - HIER_NONE/- image/png 1368113664 000000 10.56.9.27 TCP_HIT/200 639 GET http://wikid.eng.domain.com/wikid/skins/common/images/button_hr.png - HIER_NONE/- image/png 1368115000 000000 10.56.9.27 TCP_HIT/200 475 GET http://wikid.domain.com/lucene-wikid/skins/monobook/FF2Fixes.css - HIER_NONE/- text/css 1368117520 000001 10.56.9.27 TCP_HIT/200 1311 GET http://wikid.domain.com/lucene-wikid/skins/monobook/lock_icon.gif? - HIER_NONE/- image/gif 1368123877 000001 10.56.9.27 TCP_HIT/200 4099 GET http://wikid/wikid/skins/common/images/poweredby_mediawiki_88x31.png - HIER_NONE/- image/png 1368130149 000000 10.56.9.27 TCP_HIT/200 3998 GET http://wikid.eng.domain.com/wikid/skins/common/images/poweredby_mediawiki_88x31.png - HIER_NONE/- image/png Basically, Out of over 8 lac lines in the access.log of production, here is what the count for each of the type of requests it has received ..
