I have a server with large resources ( RAM, CPU, etc) running Ubuntu 20.04.
When I put squid 4.13 to manage more than 500 http_ports, it performs

Question is, how can I setup Squid or Ubuntu to use more hw resources in
order to perform better?
To make Squid perform better you need to identify and address the
current bottleneck. You are implying that the current bottleneck is tied
to the number of http_ports. If that is true, it is probably possible to
optimize Squid to handle the large number of listening ports better.
What makes you think that the number of http_ports is the culprit?
What CPU usage do you see for each Squid kid process during high load?
What percentage of RAM is used during those times?
FWIW, as you already know from past squid-users emails, I am not aware
of any linear scans of http_ports in modern Squids that could
significantly affect runtime performance. That does not mean such linear
scans do not exist, of course. However, I bet the real problem is elsewhere.
HTH,
Alex.
Or does it a matter of software architecture limitation?
Perform well with at least 500 http_ports would be very nice so we can
use smaller numbers of VPSs.
Its hard to manage so many of it.
It would be a dream to have like 10k http_ports in a single server.
If it is not possible, is there any planning about do it in a future?
Tks
Marcelo.
