We have two full tables running on mikrotik, in two different locations.

Running that command
/ip route print count-only where bgp-as-path="1234"
Replacing the AS with "33363" (local cable company).
Doesn't work on either of our routers for some reason (MT 5.0rc1 or 4.4).

Our router running a core 2 2.93ghz can take two full feeds gets all the
routes in about 4 seconds, And cpu load is idle about 13 seconds later.
However making changes with routing filters take anywhere from
10seconds to 2 minutes depending on what its doing.

Subject: [WISPA] Full BGP on RouterOS

Hi,

Does anyone have 1-2 full BGP routing tables on a MikroTik router?  If
so, what kind of hardware are you running.  I'm testing a single feed on
a P3 800.  It loads the routes fine, and seems to handle the routes in
stride (all 328659 of them), until you start poking at the routing table
like...

/ip route print count-only where bgp-as-path="1234"

An AS that yielded 500 routes took 1-2 minutes at 100% CPU to complete.
Is this "normal" these days, or is significantly greater hardware in
order?  I used to have a full feed on a Cisco 3640.  It took 5-10
minutes to load all of the routes after a reload, and it was almost
impossible to log in, high packet loss, etc. during that time.

So, should it take 10 seconds on real hardware, or is this type of query
always slow?

Thanks,
