Took your advice Frank, and put the stuff on separate subnets. Feel happier about it. I think my network is a bit over engineered for the usage its getting, but I do take your point on getting a router capable switch, will look into it.

minor correction, the bonds do not have the same IP address, since they differ in the subnet on the according VLAN. Given your config you shoud try :

192.168.1.101 on VLAN 1 … and
192.168.2.102 on VLAN2

DNS should be only one device usually. And make sure you configure your gateway IP address per VLAN according to your needs.

Best regards, frank

p.s. and perhaps consider a routing capable switch – for small money from ebay, to relief your router from the LAN routing traffic, since its routing performance does not exactly match the needs of your internal devices

]]> Comment on Speed difference of iterating forwards and backwards on a vector by Andrew Bromhead http://www.brombo.co.uk/archives/289#comment-5 Thu, 10 May 2018 21:32:41 +0000 http://www.brombo.co.uk/?p=289#comment-5 Keen observers may have noticed that the assembler pertains to GCC but as I’m doing this on a Mac I’m using clang. Using Godbolt Clang seems better.
If calculated sum is predicable clang optimises out loop and vector, but adding rand() to the sum fixes that.
In the case of -O2, the assembler looks similar to GCC.
In the case of -O3 the assembler is loop unrolled.
The conclusions however still stands.

Hi Simon,
Good to hear from you. Will add a big blog comment on it rather than reply here.
Sorry didn’t get to read what issues you were after in particular…
Please state.
