Just noticed a severe download speed degradation between 7.1.5 and 7.2rc7 using IPIP tunnel.
Tested with RB4011 at both ends, IPIPV6 tunnel,
local router running 7.1.5 :
Code: Select all
tcp-download: 379Mbps local-cpu-load:51%
tcp-upload: 334Mbps local-cpu-load:38% remote-cpu-load:57%
udp-download: 593Mbps local-cpu-load:43% remote-cpu-load:53%
udp-upload: 472Mbps local-cpu-load:43% remote-cpu-load:43%
Code: Select all
tcp-download: 277Mbps local-cpu-load:43%
tcp-upload: 292Mbps local-cpu-load:41% remote-cpu-load:46%
udp-download: 238Mbps local-cpu-load:17% remote-cpu-load:32%
udp-upload: 440Mbps local-cpu-load:60% remote-cpu-load:32%
Note : with 7.2rc7 it seems that only one core is actually used.
(not so obvious in above benchmark, but very clear with "/system/resource/monitor" on several other tests)
Besides, fastrack on/off, firewall filter/mangle rules or minimal, does not make a significant difference.
