<p style="margin-bottom: 0in; line-height: 100%">Hi Folks!</p>
<p style="margin-bottom: 0in; line-height: 100%"><br>
</p>
<p style="margin-bottom: 0in; line-height: 100%">First, thanks for
the assistance in the past; has resolved a lot of issues.
Hopefully
can get this one resolved also, probably just something simple I
don’t understand while trying to do my own troubleshooting.</p>
<p style="margin-bottom: 0in; line-height: 100%"><br>
</p>
<p style="margin-bottom: 0in; line-height: 100%">Have two Backends –
separate IPs and passwords. Wanting to switch to the “new and
improved” Backend with better specs and before the old Backend’s
motherboard fails. The old system is “BE1” and the
new/replacement is “BE2”. So when a (remote) Frontend looks at
BE1 (old) it plays nice, Fast Forward through commercials is
snappy,
all is well. Same Frontend on BE2 (new), playback is fine but when
hit FF it sits at 3x for a second or two (same frame), then (say)
20
or 30x and the frame is jump-pause-jump-pause – probably takes two
or three times as long to get through commercials with the new
system
as the old, which has a lot faster processor: BE2: AMD Athlon II
X2 250 Processor – dual core @ 3010.387 MHz, Mythbuntu 64 bit. Did
the add ppa for 0.28/ update/upgrade/reboot steps this morning;
didn’t help the FF sluggishness problem.</p>
<p style="margin-bottom: 0in; line-height: 100%"><br>
</p>
<p style="margin-bottom: 0in; line-height: 100%">On the System
Information page with the BE Status:</p>
<p style="margin-bottom: 0in; line-height: 100%"> Machine Status
(@
BE2) (while two shows recoding):</p>
<p style="margin-bottom: 0in; line-height: 100%"> RAM: 15 GB
total,
5.8 GB used, 9.6 (or 62%) free.</p>
<p style="margin-bottom: 0in; line-height: 100%"> Swap: 3.7 GB,
0
KB used, 3.7 GB (or 100%) free.</p>
<p style="margin-bottom: 0in; line-height: 100%"><br>
</p>
<p style="margin-bottom: 0in; line-height: 100%">What may be a
little
odd is exit and look at System Monitor (at Desktop) it’s graph
barely indicates any RAM usage: around 1.0 GiB of 15.4 GiB.
Running
SysMon, load mythfrontend via Terminal … exit, so SysMon still
running. (Swap is 0 bytes at 3.7 GiB.) Both cores show I guess
lowish use: right now something is recording and both cores
‘wobbling’ about 15-20% usage. (Later: Recording finished: now
both cores idling 0 – 4%.)</p>
<p style="margin-bottom: 0in; line-height: 100%"><br>
</p>
<p style="margin-bottom: 0in; line-height: 100%">Both Backends
connect to the LAN via the same switch, both are gigabyte LANs.
Have
tested with four Frontends (one a Raspberry Pi 3 I’m working on):
BE1, no problem, nice and smooth; BE2, playback is fine but FF,
Rewind, and Commercial Rewind (title?) is jumpy/staccato and
sluggish.</p>

<p style="margin-bottom: 0in; line-height: 100%">Miscellaneous
thoughts:</p>
<p style="margin-bottom: 0in; line-height: 100%"><br>
</p>
<p style="margin-bottom: 0in; line-height: 100%">(1) Found how to
test the NIC speed: </p>
<pre class="western"><code class="western"> </code><code class="western">sudo ethtool </code><code class="western">enp4s0</code><code class="western"> | grep -i speed</code> ==> Speed: 1000Mb/s</pre>

<p style="margin-bottom: 0in; line-height: 100%">(3) Also had tried
turning off the Frontend portion on the Backend (BE2) – saw
comments in the above webpage about a misconfiguration.</p>

<p style="margin-bottom: 0in; line-height: 100%">...OK, enough of my
trying to give you folks enough information to make informed
suggestions. TIA!</p>
