Subject: [MMTests] Sysbench read-only on ext4
Date: Mon, 23 Jul 2012 22:14:44 +0100 [thread overview]
Message-ID: <20120723211444.GB9222@suse.de> (raw)
In-Reply-To: <20120629111932.GA14154@suse.de>
Configuration: global-dhp__io-sysbench-large-ro-ext4
Result: http://www.csn.ul.ie/~mel/postings/mmtests-20120424/global-dhp__io-sysbench-large-ro-ext4
Benchmarks: sysbench
Summary
=======
Looking better in places than ext3 but still of concern.
Benchmark notes
===============
mkfs was run on system startup. No attempt was made to age it. No
special mkfs or mount options were used.
sysbench is an OLTP-like benchmark. The test type was "complex" and
read-only. The table size was 50,000,000 rows regardless of memory size
but far exceeds the memory size of any of the test machines. sysbench
was chosen because it's a reasonably complex OLTP-like benchmark with
straight-forward prerequisites.
The backing database was postgres.
===========================================================
Machine: arnold
Result: http://www.csn.ul.ie/~mel/postings/mmtests-20120424/global-dhp__io-sysbench-large-ro-ext4/arnold/comparison.html
Arch: x86
CPUs: 1 socket, 2 threads
Model: Pentium 4
Disk: Single Rotary Disk
===========================================================
sysbench
--------
Generally regresssed.
Swapping for kernels 3.1 and 3.2 is very high.
==========================================================
Machine: hydra
Result: http://www.csn.ul.ie/~mel/postings/mmtests-20120424/global-dhp__io-sysbench-large-ro-ext4/hydra/comparison.html
Arch: x86-64
CPUs: 1 socket, 4 threads
Model: AMD Phenom II X4 940
Disk: Single Rotary Disk
Status: Ok
==========================================================
sysbench
--------
For low number of clients, this has generally improved.
Swapping in kernel 3.1 was high.
==========================================================
Machine: sandy
Result: http://www.csn.ul.ie/~mel/postings/mmtests-20120424/global-dhp__io-sysbench-large-ro-ext4/sandy/comparison.html
Arch: x86-64
CPUs: 1 socket, 8 threads
Model: Intel Core i7-2600
Disk: Single Rotary Disk
Status:
==========================================================
Generally this is telling a much better story but this could be because
of the much larger memory size of this machine offsetting some other
regression.
Swapping in 3.1 and 3.2.
