Hello
Please tell me additionally.
4. I only know Squid up to 3000 users.
Is there any case where Squid is used by a company that is used by more than 30,000 users?
Please let me know if there is a large company using Squid.
5. What are the important point when using the "wokers" setting for multiple processes?

Hello,
I'm planning a proxy renewal for a company with 45k clients.
I'm looking at the performance of a single Squid to determine the number of Squids.
Environment: Virtual (OpenStack)
OS: CentOS8.1
CPU: 4 cores
MEM: 8GB
DISK: SATA30GB / 100GB
Squid 4.4
SSL Bump
Blacklist: 1,700k
auth: NTLM
cache: 4GB
In an environment with authentication disabled and SSL decoding enabled
A load test was performed with Jmeter.
Result: CPU high load (100rps-1000rps: CPU Usage 80-90%)
(Confirm with top command)
Added multi-core support settings to squid.conf
"workers 4"
A load test with Jmeter was performed again.
Result: CPU load is distributed to 4 cores (CPU Usage 20-40%)
(Confirm with top command)
Question
1. 1. How much will CPU Usage increase if NTLM authentication is enabled?
2. 2. Are there any concerns other than CPU Usage in Squid?
3. 3. When I enabled the cache in this test, the CPU Usage decreased, but in general, does the Squid cache increase the CPU Usage?
Thank you,
Kitamura
