Analyzing the Timeline of my website – TOC+ is one of the slowest plugins to load – now of course this will only apply to logged in users – as non logged in get to see a cached page – but I wonder why the plugin seemingly (I may be wrong and misunderstand something) needs to run database queries on every page load.<\/p>\n\n\n\n

Overall the queries on my relatively plugin heavy site take about 0.20 seconds – But TOC+ alone takes around 0.01-0.02 seconds for it’s query. Yes it’s not render blocking so no essential slowdown as other queries are started in parallel – but I feel this is quite long for something not depending on external sources to load. And it’s the slowest query of all queries on my website by quite some margin. Most queries need only 1\/10 of the time or less.<\/p>\n\n\n\n

The offending query is:<\/p>\n\n\n\n

WHERE<\/strong>\u00a0option_name<\/code> =\u00a0‘_transient_timeout_aioseo_plugin_cache_table_exists’<\/p>\n\n\n\n
