CRS328 / high CPU-Lod SPI

Sat Aug 06, 2022 10:32 am

Hi,

does anyone know why the process "SPI" creates such a high CPU-Load? Sometimes it goes up to 100%
I have read this is LED related, but the CRS328 does not have a LED screen.

The config is 1:1 the same as on a replaced CRS326, this never showed SPI.

If I were an editor and someone asked me to evaluate which are the "slow" parts of the tale,
I wouldn't have at least the text to read???

Starting from the fact that you have censored a private IP in the 10.x.x.x/8 range, already tells me so much about your knowledge.
But a book by the cover should not be evaluated, NO?

The question is, what is SPI at first? MT does not clarifiy?
https://wiki.mikrotik.com/wiki/Manual:Tools/Profiler

Normally SPI stands for "Stateful Packet Inspection" but this device is configured as a simple switch, no NAT, no filter, no mangel... So SPI must be something different. Maybe someone knows?

@rextended, why are you never give a sensible reply? Whats wrong to hide my exact private IP scheme? All information I give, is the device is configured in accordance to RFC1918. https://www.rfc-editor.org/rfc/rfc1918.html There is something like "Security through obscurity" https://en.wikipedia.org/wiki/Security_ ... _obscurity But I dont expect you know something.

Because you do not provide any sensible question?

If instead of wasting time unnecessarily obscuring 10.8x.x.x, and instead you published the export to see what made you "use" ( :twisted: ) the spi,
which maybe you hadn't noticed, it was better.
There is something like "Security through obscurity" https://en.wikipedia.org/wiki/Security_ ... _obscurity
Surely hiding your internal private IP, which only you use in the world, is a matter of national security.
I forgot how important it is to keep that highly traceable IP hidden that other 1000 devices have.

As chechito says. The flash memory sits on the SPI-bus. Are you using the flash memory for something?
