+Subject: WFE - reducing wait between WFE invocations from 10s to 2s
+
+All,
+
+in order to minimise CTA request pileups, I have reduced the wait time between
+WFE invocations from 10s (default) to 1s. This way, WFE will be running more
+often, but finding (and therefore processing) less jobs in the incoming /q/
+queue. It should help minimising overloads.
+
+[root@p06253947b39467 mgm]# eos space config default space.wfe.interval=1
+success: setting wfe.interval=1
+
+cheers, Germán
