I would aim for totally disabling disk swap, but getting to that configuration is easier if you keep swap enabled and consider any non-trivial swap use as a problem that you need to fix. After all non-trivial swap uses are eliminated, it does not really matter much whether you keep swap enabled or not! Please note that this suggestion is specific to performance-sensitive Squid servers -- many other servers have very legitimate reasons to use swap. YMMV. > That setting on production can be disaster. Squid swapping in production is an arguably worse disaster, as you have learned. In many cases, it is better to deal with a lack of swap than to rely on swap's magical effects that most humans poorly understand. YMMV. > We will try, we reduced number of auth helper, prolong ldap caching. > Little steps but at last every bit counts. ... unless those bits are actually hurting. You may need to understand your server memory usage better to reduce the time spent on trying random changes. For example, if auth helpers are close to being overloaded, reducing their number may make things worse.
