9 content recommendations that are too slow

I built a wordpress website and found that the speed is too slow. The mainstream optimization is just to reduce plug-ins, optimize static resources, staticize website pages, etc. But for a website without plug-ins, use the default theme, and the PHP file itself requires all requests. It takes more than 1 second (excluding resource file loading). Is this normal? Is this pot for WP or PHP? I haven’t looked at the WordPress code in detail (because I’m not very familiar with PHP), but I looked at the WP database and found that there are only a few tables. Then I was thinking about so many websites based on WP extensions. Are those customized attributes? Is it implemented through post_meta? If this is the case, will each get_post_meta trigger a query, in which case a page will be very slow. I don’t know if this is the case? After disabling all plug-ins and changing to the default theme, as shown above, it seems that the database query time is not very long. Why is the TTFB so big?

4. Nginx configuration ssl encryption (single and two-way authentication, partial https) nginx tomcat https nginx https proxy nginx configuration https generation

Introduction: nginx, https: Nginx configures SSL encryption (single and two-way authentication, partial https): Configuring SSL under nginx is originally very simple, whether you go to the certification center to buy an SSL security certificate or a self-signed certificate, but recently the company A requirement of OA, I have a chance to actually play around with it. At first, whole-site encryption was adopted, and all requests to access http:80 were forcibly converted (rewritten) to https. Later, the automated test results said that the response speed was too slow. https was 30 times slower than http. I thought how could it be possible? Do you know how they do it? Measured. So I tried some pages https (cannot be encrypted only for certain types of dynamic requests) and two-way authentication

Looking for a function that can quickly generate a histogram using PHP. It is currently too slow to complete a simple function. As a beginner, I can only manipulate CSS to generate a simple histogram, but my function is extremely slow when the data is more than 25,000.
