The virtual domain name configured by wamp is very slow.

What is the possible cause? sometimes, when I get a computer from 404 of my colleagues and request it for a while, I don't need it. my environment is very slow, I don't need to ask if Apache and php configuration is wrong after a request of about 30 s, except for slow speed.

What is the possible cause?
Sometimes I get some 404 colleagues' computers and request them for less than a while. my environment is very slow and it takes about 30 s to request them.

Ask Apache and php if the configuration is wrong.
What are other problems besides slow speed?

It may be that the concurrency settings are too low.
