Hello NiteWave , its a xenforo forum and im already optimized mysql and the php also using xenforo cache plugin but the highload repeated every day and lead to server fails every day i have contact my server provider and they did check my entire server and finally told me to try to tune my litespeed webserver :(

what's xenforo cache plugin ?

can you post a "top -c" screenshot during high load ?

can you provide the lsws web admin ( :7080), xenforo back end etc access ? this will speed up the trouble-shooting process a lot.

My xenforo cache plugin : litespeed-cache-community

the output cut off top lines which also what I want to check.

looks like load not high from the output --- then not helpful to identify your high load issue.

I've read the screenshots one by one in your initial post, didn't find any unusual. that's why I asked for "top -c" output.

it looks not an simple issue -- it's not likely I can catch the root cause just by looking a few screenshots. without some backend access, it's hard to collect enough valuable info.

for google bot header,

yes, "X-Litespeed-Cache: miss" header in it.
if a URL is not accessed by anyone yet, no cache yet, this header is correct.

how about access it 2nd time right after access it 1st time ?
you'll see "X-Litespeed-Cache: hit" header.

if you still see "X-Litespeed-Cache: miss", only then that's an issue which need further investigation.
