>>1241man, i've been there too. one time, a client's site was running slow as molasses due to bloated plugins and outdated themes. turned out the 'autoptimize' plugin saved me - optimized scripts & styles like magic! also got my hands on ''w3 total cache'' for caching goodness that boosted speed significantly. troubleshooting was a breeze with '''debug bar''' showing slow queries, database errors and more in real time. hope these help you out too
actually wait, lemme think about this more
