Proxy Backup speed
-
Hi all,
Im currently testing the use of a XOA Proxy to utilise remote backups. We'd eventually like to use x2 proxies at various sites for backups.
To test our Proxy is currently in a place where it saves a couple of hops compared to XOA and it traverses all the same networking kit as our XOA.
As you can see from the images below, backing up from our main XOA VM is x3 faster than the proxy.
Both XOA and Proxy have 16GB/8GB RAM respectively and 4 CPUs assigned.
Is there anything I can do to speed up the Proxy/ settings that can be changed etc?
Cheers

That's really weird. You shouldn't have any "pure perf" diff (outside the network path), because the code is the same in theory
Any thought @julien-f?

@olivierlambert I'm currently not sure what's causing it to be slower (and by that much). I've ran other backup tests and I am getting similar results.
Even taking into account the time of day I ran the test vs our normal OOHs backups it's quite a difference.
Switches aren't being anywhere near utilised during the backups (10GBE / 40GB Fibre between hops).
XOA and proxy are up to date "Current version: 5.66.2 - XOA build: 20210823"

Is it roughly the same hardware behind XOA and Proxies?
-
@olivierlambert It's exactly the same - this was deliberate at the time. Much easier to troubleshoot if all your hosts are the same spec!

Frankly I have no idea
@julien-f might have a theory, I hope

@olivierlambert XO and XO Proxy are using the same code and the same backup workers to run backup jobs. If there are differences in perf, IMHO, they come from the appliances themselves and/or their networks.
Keep in mind that data flows from the host, via XO or XO proxy, to the remote storage. Maybe the proxy is further from the host and/or the remote regarding the network?
