Re: [AFMUG] CPU - when to upgrade
My rule of thumb is >50% = upgrade. I wouldn't argue with 25% either. We see a % CPU usage which updates every second. I don't know if it's a 1 second average, or a rolling 5 second average, or whatever. Either way there could be milliseconds within that average where all CPU time is occupied and it wouldn't show in the display. If we're trying to carry traffic which is sensitive to milliseconds of delay (VoIP) then my feeling is ought to be safer to keep the CPU usage low. I have no data to back this up. It's basically just the philosophy that I'd rather have it and not need it than need it not have it. -- Original Message -- From: "Mathew Howard" To: "af" Sent: 4/5/2018 9:10:41 PM Subject: Re: [AFMUG] CPU - when to upgrade I start getting paranoid if I see more than about 25% CPU load on a Mikrotik... whether or not that's actually having any impact on performance, I don't know, but I suspect at 70% it is - I would certainly upgrade it to something faster at that point.

Re: [AFMUG] CPU - when to upgrade
No, they'll go high enough for MPLS/VPLS, it's just limited to 1580, which is a lot lower than most of the other Mikrotiks.

Re: [AFMUG] CPU - when to upgrade
I really want…
A MikroTik
About the size of 3011
12 – 16 ports with POE out on all ports (24v and 48v) regulated so not to
release the magic ubnt smoke
1ghz + cpu
DC input
A build in battery charge controller (wishful thinking)
:-)

Re: [AFMUG] CPU - when to upgrade
I would avoid the 850gx2... the new hEX (RB750Gr4, I think... maybe gr4), is much faster and cheaper, and it doesn't have the MTU limitations the 850Gx2 has. A 3011 in a 2011 case is a good drop in replacement for a 2011 (assuming you don't have room for the rackmount case the 3011 comes in). The HEX POE (not the Lite version), is also much faster than the 2011 (the non-poe version is a bit faster though). I really wish they sold the 3011 in the 2011-style desktop case, but if you're replacing a 2011, it's simple enough to swap cases. the RB3011 is the fastest thing until you go up to an 1100ahx4, or CCR (which are both much larger, and more expensive).
