It helped. My tech wrote to me:
I truncated the table, which had many records, which seemed to resolve the issue.curl -s -o /dev/null -w ‘TTFB=%{time_starttransfer}\n’ MYURL
TTFB=0.535 << LOADING .5 seconds again
I also added the code to your theme’s functions.php file to keep the table from slowing things down again, as per their instructions.
Thank you for responding so promptly. I’ve relayed this to my web tech for review and I’ll let you know how it goes.
