When trying to reuse a backend connection, a connection hash is calculated to match an entry with similar parameters. Previously, this operation was skipped if the stream content wasn't based on HTTP, as it would have been incompatible with http-reuse. With the introduction of SPOP backends, this condition was removed, so that it can also benefit from connection reuse. However, this means that now hash calcul is always performed when connecting to a server, even for TCP or log backends. This is unnecessary as these proxies cannot perform connection reuse. Note also that reuse mode is resetted on postparsing for incompatible backends. This at least guarantees that no tree lookup will be performed via be_reuse_connection(). However, connection lookup is still performed in the session via session_get_conn() which is another unnecessary operation. Thus, this patch restores the condition so that reuse operations are now entirely skipped if a backend mode is incompatible. This is implemented via a new utility function named be_supports_conn_reuse(). This could be backported up to 3.1, as this commit could be considered as a performance regression for tcp/log backend modes. |
