We updated to rrdtool 1.5.5 from 1.4 the other day and since then
have noticed dramatic slow down.<br>
<br>
I just did some benchmarks and talking to rrdcached over a network
socket (same host) to do 862 fetches took 91.388106 seconds e.g.<br>
FETCH 351918.rrd AVERAGE 1460244557 1460244917<br>
<br>
The same over local unix socket took 0.097147 seconds so it looks
like there's been a major performance regression in 1.5 from 1.4?<br>
<br>
When we initially updated the client before our rrdcached server we
did see errors with:<br>
rrdcached: Unknown command: FETCH<br>
<br>
So I'm wondering if rrdcached FETCH is new 1.5 hence the issue.<br>
<br>
Previously we were running: rrdtool 1.4.8<br>
<br>
Anyone got any ideas?<br>
<br>
