Does adding too many entries to the hosts file causes internet slow down?

Question

I just wanted to clarify one thing, Does adding too many entries to the %windir%/system32/drivers/etc/hosts causes internet slow down?

Does duplicate hosts entry slows down browsing performance?

What will happen if I delete the hosts file, will it speedup browsing speed?

I'm using windows 10

Answer 1

I don't think so.The hosts entry would be written to DNS cache.It makes Name resolution faster.

You could delete or reset the hosts file to prove it.
