CRS112 performance and strange bahaviour

Wed Jul 27, 2016 12:02 pm

Hello
We tried to use CRS112 for the first time. It appeared that while adding any routing ( even simple ) the performance of CRS is drastically reduced and CPU load goes up to 100% almost all the time.
I have question: is it normal in CRS112 that after reset to default all files in the flash are wiped out ?

CRS112 is _very_ limited in routing performance. the CPU is weak.
also, the "new" mikrotik way of disk-handling is different, so stuff must be in non-volatile part, which is flash/xxxx

[admin@probe01] > /file print 
 # NAME                   TYPE                        SIZE CREATION-TIME       
 0 flash                  disk                             jan/01/1970 02:00:00
 1 scan.wlan2.1468585560  .1468585560 file            1400 jul/15/2016 14:24:44 <-- will disappear on reload
 2 flash/skins            directory                        jan/01/1970 02:00:01
 3 flash/MikroTik-2016... backup                   36.8KiB may/26/2016 15:18:23 <-- will be permanent

Yes but the catch is that all what was inside flash/ is also wiped

And do I miss something ? I just tested my old 2011 upgraded to 6.36 and there is no /flash folder and nothing is wiped after reset.

2011s have different file structure. and it has NAND flash.

you have the flash there accessible as "/file"
in the more recent platforms with usually less flash in there, /file points to a ram-disk, and the actual flash
contents are accessible in the sub-directory called flash. everything else will disappear on reboot.

early CRSes had also quite large (128MB) NAND flash.
CRS112 has SPI flash (as almost everything since hAP lite), and is significantly smaller now. (16MB)
discussion about this: http://forum.mikrotik.com/viewtopic.php?f=3&t=106195

you can also check it out on routerboard.com, some boxes have storage listed as NAND, the newer stuff
has it shown as FLASH.

anyway, the issue you described is strange, it shouldn't be so.

If you want something similar to RB2011, you should get CRS109 or CRS125.
