Amos san, Alex san, Thank you for your reply.
Change squid to compile from source. Also change the NTLM authentication to KRB. I understand that error and response speed are more important than CPU. The CPU is not 100%, but the number of simultaneous connections does not exceed 450. In netstat, FIN_WAIT was over 10000. Is there a way to reduce FiN_WAIT? Also, can socks proxy be used with squid? If not, what are you using as an alternative? thank you, kitamura 2020年10月2日(金) 23:09 Alex Rousskov <rouss...@measurement-factory.com>: > On 10/2/20 1:26 AM, m k wrote: > > > > > Is there any case where Squid is used by a company that is used > > > by more than 30,000 users? > > > > Yes, some Squid (hierarchies) probably serve millions of users.
