ARM processors? Practice. Marvel Armada XP

First of all, I would like to thank Rikor and Oleg personally for providing platforms for testing. As before, you can take on the Marvell Armada XP test for yourself and later, as a tester, keep them in use for a nominal fee. As promised in the last article Server on ARM? Made in Russia! - I give server performance tests on ARM processors. Since ARM is a processor made by System-On-Chip technology, we will focus our attention on processor performance.
There are many tests in the World Wide Web, but they are all for us, like a fantastic trip to Mars - how they were carried out, what kind of revisions the processor (or just another manufacturer), what software was used is not clear. And here - the server in front of us, it remains only to test.



Test benches:
')
1) Core2 Quad:

OS: CentOS release 5.7
Processor: 4-core Intel® Core (TM) 2 Quad CPU Q9450 @ 2.66GHz
RAM: MemTotal 3939800kB

2) Atom D510:

OS: Ubuntu 04.04.3
Processor: 2-core Intel® Atom (TM) CPU D510 @ 1.66GHz, 4-threads
RAM: MemTotal 4032060kB

3) Marvell Armada XP:

OS: Ubuntu 04.04.3
Processor: 4-core Marvell PJ4Bv7 Processor rev 2 (v7l)
RAM: MemTotal 8019640 kB

Hard drives in all three WD black booths. The RAM in Core 2 Quad and Atom D510 costs the maximum amount.

sysbench - processor test

The test was launched in 4 threads and in 10,000 requests to the processor.

OLTP testing - MySQL performance with sysbench

First we create an innoDB table for 10,000 records. By team

sysbench —test=oltp —mysql-table-engine=innodb —oltp-table-size=10000 —mysql-user=root —mysql-password=root —db-driver=mysql —test=oltp prepare

Then the team

sysbench --num-threads=8 --max-requests=500 --oltp-table-size=10000 --mysql-user=root --mysql-password=root --db-driver=mysql --test=oltp run

Perform a test with 8 clients (the maximum number of queries is 500) on the table that was created in the previous step.

Test output:





For comparison, we take three indicators: transactions (transactions), read / write requests (read / write requests), other operations (other operations).
The value of deadlocks is not taken, because it is the same on both platforms and is zero.

Archiving information with 7zip

Archive will be 1GB of randomly created data.

du -sh /tmp/ramfs/file
1.0G /tmp/ramfs/file
time 7za a dummy -mmt=4 -txz -so /tmp/ramfs/file | dd of=/dev/null


Compression and decompression tests in 7zip

For the graph, take the average value of the speed of compression and decompression.

Performance testing with Openssl speed

Due to multiprocessing (4 processes running at the same time), the benchmark output is not readable, but the essence lies in the calculation of various types of encryption. Here we need the total time of the assignment and the last part of the program output.

With the help of Phoronix Test Suite we will test the processors of our platforms

Conclusions from tests everyone can make for himself. Our findings are that ARM is at the Atom D510 level. At the same time, ARM consumes significantly less energy and has quite a good potential, since the adaptation to the architecture is just beginning, and we all look forward to Aarch64 (ARM64).

In the next article we plan to bring the results of testing the work of various applications on the ARM platform. The plans of various hosting control panels, various CMS. If you want to test something, write to zbg@globatel.ru
