Re: Is ARM64 officially supported ?

[dormando]

Hey,

Sorry I missed this (almost two months ago?)

If I were to do a serious performance comparison for ARM right now it
would have to be a sponsored project; I can't justify the time out of
personal curiosity right now :)

If you want some detailed analysis contact me privately and we can
discuss.

If you're still stuck I'll write more of a guide, just let me know.

Hey,

I thought I wrote this in the rest of the e-mail + the README: it doesn't
print stats at the end. you run the benchmark and then pull stats via
other utilities. Take a close look at what I wrote and the files in the
repo.

What I miss to find so far is how to get the statistics after a run.
For example, I run
./mc-crusher --conf ./conf/asciiconf --ip 192.168.1.43 --port 12345
--timeout 10

and the output is:

--
ip address default: 192.168.1.43
port default: 12345
id 0 for key send value ascii_get
id 1 for key recv value blind_read
id 5 for key conns value 50
id 8 for key key_prefix value foobar
id 26 for key key_prealloc value 0
id 24 for key pipelines value 8
id 0 for key send value ascii_set
id 1 for key recv value blind_read
id 5 for key conns value 10
id 8 for key key_prefix value foobar
id 26 for key key_prealloc value 0
id 24 for key pipelines value 4
id 19 for key stop_after value 20
id 3 for key usleep value 1000
id 12 for key value_size value 10
setting a timeout
done initializing
timed run complete
--

And I see that the server is busy at that time.
How to find out how many sets/gets/... were made ?

Re: Is ARM64 officially supported ?

[dormando]

memtier is trash. Check the README for mc-crusher, I just updated it a bit
a day or two ago. Those numbers are incredibly low, I'd have to dig a
laptop out of the 90's to get something to perform that badly.

mc-crusher runs blindly and you use the other utilities that come with it
to find command rates and sample the latency while the benchmark runs.
Almost all 3rd party memcached benchmarks end up benchmarking the
benchmark tool, not the server. I know mc-crusher doesn't make it very
obvious how to use though, sorry.

A really quick untuned test against my raspberry pi 3 nets 92,000
gets/sec. (mc-crusher running on a different machine). On a xeon machine
I can get tens of millions of ops/sec depending on the read/write ratio.

Re: Is ARM64 officially supported ?

[Martin Grigorov]

Hi

I've made some local performance testing

First I tried with https://github.com/memcached/mc-crusher but it seems it
doesn't calculate any statistics after the load runs.

The results below are from https://github.com/RedisLabs/memtier_benchmark

1) Text
./memtier_benchmark --server XYZ --port 12345 -P memcache_text

ARM64 text

Totals  10827.28 0.00  9842.00 20.02000   316.05

Totals  10231.26 0.00  9300.21 20.30200   298.66



2) Binary
./memtier_benchmark --server XYZ --port 12345 -P memcache_binary

ARM64 binary
=
Type Ops/sec Hits/sec   Misses/sec  Latency   KB/sec
-

Text is faster on the ARM64. Binary is similar for both.

The benchmarking tool runs on different machine than the ones running
Memcached:

The ARM64 server has this spec:

My manager confirmed that we can give you access to an ARM64 machine. VM
would be easier to setup but bare metal is also possible.
Please tell me the specs you prefer.
We can give you access only temporarily though, i.e. we will have to shut
it down after you finish the testing, so it doesn't stay idle and waste
budget. Later if you need it we can allocate it again.
Would this work for you ?

I will talk with my managers!
I think it should not be a problem to give you a SSH access to one of our
machines.
What specs do you prefer ? CPU, disks, RAM, network, ...
VM or bare metal ?
Preferred Linux flavor ?

It would be good to compare it against whatever AMD64 instance you have. Or
I can also ask for two similar VMs - ARM64 and AMD64.

Re: Is ARM64 officially supported ?

[Emilio Fernandes]

Hola Dormando!

Thank you for confirming that ARM64 is officially supported!
Do you think it would be a good idea to mention the list of the supported 
platforms somewhere on the website or at least in GitHub Wiki ?

I don't think my employer could donate ARM64 hardware :-/ Sorry!

Gracias!
Emilio

Re: Is ARM64 officially supported ?

[dormando]

Yo,

Just to add in: yes we support ARM64. Though my build test platform is a
raspberry pi 3 and I haven't done any serious performance work. packet.net
had an arm test platform program but I wasn't able to get time to do any
work.

>From what I hear it does seem to perform fine on high end ARM64 platforms,
I just can't do any specific perf work unless someone donates hardware.

I am not aware of any public benchmark results for Memcached on AMD64 vs
ARM64.
But quick search in Google returned these promising results:
1) https://github.com/memcached/mc-crusher
2) https://github.com/scylladb/seastar/wiki/Memcached-Benchmark
3) https://github.com/RedisLabs/memtier_benchmark
4) http://www.lmdb.tech/bench/memcache/

I will try some of them next week and report back!

Martin

Re: Is ARM64 officially supported ?

[Emilio Fernandes]

Thank you for sharing your experience, Martin!

I've played for few days with Memcached on our ARM64 test servers and so 
far I also didn't face any issues.

Do you know of any performance benchmarks of Memcached on AMD64 and ARM64 ? 
Or at least of a performance test suite that I can run myself ?

Gracias!
Emilio

Re: Is ARM64 officially supported ?

[Martin Grigorov]

Hello Emilio!

Welcome to this community!

I am a regular user of Memcached and I can say that it works just fine for
us on ARM64!
We are still at early testing stage but so far so good!

I like the idea to have this mentioned on the website!
It will bring confidence to more users!

Martin

Is ARM64 officially supported ?

[Emilio Fernandes]

Hello Memcached community!

I'd like to know whether ARM64 architecture is officially supported ?
I've seen that Memcached is being tested on ARM64 at Travis but I do not 
see anything on the website or in GitHub Wiki explicitly saying whether it 
is officially supported or not.

Gracias!
Emilio
