My Magento Store that I have taken over my another dev is currently displaying a high Time to First Byte (TTFB) of around 1s. I'm aware that lots more goes into this number that SQL queries alone, however after running the Magento SQL profiler it shows that when index.php loads around 350 SQL queries are executed, amounting to around 0.50 s in processing time.
I want to start optimizing this to improve the page load times. I have a relatively good understanding of MySQL but am new to Magento. Where should I go about looking to start tuning or removing/replacing some of these queries to try and improve page load times? Thanks!
