From 9977c7e5fabd8c94f11d06b1cce6cf18277bb91c Mon Sep 17 00:00:00 2001 From: Artem Boldariev Date: Tue, 25 Feb 2025 19:58:24 +0200 Subject: [PATCH] DoH: Bump the active streams processing limit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit bumps the total number of active streams (= the opened streams for which a request is received, but response is not ready) to 60% of the total streams limit. The previous limit turned out to be too tight as revealed by longer (≥1h) runs of "stress:long:rpz:doh+udp:linux:*" tests.
