Re: [akka-user] remoting comparison: Artery vs Netty

[Patrik Nordwall]

What is the unit of the values in the table, e.g. 416? I guess it's milliseconds?

That doesn't match our tests at all. We have measured 800k msg/s for the 100 byte payload.

I'd recommend that you use something bigger than micro instances. Corresponding to 4 cores at least. I don't know how much the far apart regions matters, we have only tried in same zone.

Hi guys. We are migrating our application from akka 2.4 to 2.5 and among other there is new remoting available.
The throughput Before switching from netty to artery we decided to compare them.

So I created the app with two modules: sender & receiver with 16 remote actors spawned by sender on receiver side.
The finished transmission is that one in which the payload delivered to receiver and message id returned to sender.

The tests implemented as a series of messaging batches. Each batch consisted of 1000 message transmissions of K bytes (per message).
I tested it with messages of 100 byte, 1000 byte, 10000 byte with different idle-cpu-level.
With 100 byte message the artery's throughput looks better than netty's (up to 26%), but for the rest it seems that netty beat artery (40% for 1k message and 60% for 10k message).

Some info about test execution:
- warm up the system with 50 batches of 100 bytes messages;
- measure the average for 100 batches of 100 bytes messages;
- measure the average for 50 batches of 1000 bytes messages;
- measure the average for 115 batches of 10000 bytes messages;

I tested it on AWS micro instances in different regions.

Is it expected results?

idle-cpu-level is represented as Artery X, e.g. Artery 1

AWS micro instances (singapore ↔ frankfurt)
messages / bytes per message	Artery 1	Artery 3	Artery 5	Artery 7	Artery 9	Artery 10	Netty
1k / 100	441	400	416	445	466	969	543
1k / 1k	1655	1671	1674	1790	1755	3728	1217
1k / 10k	14005	15237	19142	19463	20833	37539	8565

Likely bottlenecked either by network or serialization method (or quite possibly both?).
