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?</span> <br><div><br></div><div>Kitamura</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">2020年10月2日(金) 11:15 m k <<a href="mailto:tamurin0525@gmail.com">tamurin0525@gmail.com</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello,<br><br>I'm planning a proxy renewal for a company with 45k clients.<br>I'm looking at the performance of a single Squid to determine the number of Squids.<br><br>Environment: Virtual (OpenStack)<br>OS: CentOS8.1<br>CPU: 4 cores<br>MEM: 8GB<br>DISK: SATA30GB / 100GB<br>Squid 4.4<br> SSL Bump<br> Blacklist: 1,700k<br> auth: NTLM<br> cache: 4GB<br><br>In an environment with authentication disabled and SSL decoding enabled<br>A load test was performed with Jmeter.<br><br>Result: CPU high load (100rps-1000rps: CPU Usage 80-90%)<br>(Confirm with top command)<br><br>Added multi-core support settings to squid.conf<br>"workers 4"<br><br>A load test with Jmeter was performed again.<br><br>Result: CPU load is distributed to 4 cores (CPU Usage 20-40%)<br>(Confirm with top command)<br><br>Question<br>1. 1.
