Subject: dbench throughput(sync, reflink=0|1) on xfs over hardware throughput
Date: Tue, 13 Oct 2020 23:56:11 +0800 [thread overview]
Message-ID: <20201013235609.EFC0.409509F4@e16-tech.com> (raw)
Hi,
#any reply, please Cc: wangyugui@e16-tech.com
dbench throughput(sync, reflink=0|1) on xfs over hardware
throughput(6Gb/s=750MB/s).
Is this a bug of xfs sync? or some feature of performance optimization?
we test mkfs.xfs -m reflink=0|1, crc=0|1, still over hardware
throughput(6Gb/s=750MB/s).
Disk: TOSHIBA PX05SMQ040
This is a 12Gb/s SAS SSD disk, but connect to 6Gb/s SAS HBA,
so it works with 6Gb/s.
dbench -s -t 60 -D /xfs 32
#Throughput 884.406 MB/sec (sync open)
dbench -s -t 60 -D /xfs 1
#Throughput 149.172 MB/sec (sync open)
we test the same disk with ext4 filesystem,
the throughput is very close to, but less than the hardware limit.
dbench -s -t 60 -D /ext4 32
#Throughput 740.95 MB/sec (sync open)
dbench -s -t 60 -D /ext4 1
#Throughput 124.67 MB/sec (sync open)
linux kernel: 5.4.70, 5.9.0
