Linux를 사용하는 경우 Flexible IO Tester (fio) 도구를 사용하여 기본, 리전, 영역, 엔터프라이즈 등급 인스턴스의 읽기 처리량, 쓰기 처리량, 읽기 IOPS, 쓰기 IOPS를 벤치마킹할 수 있습니다.
단일 클라이언트 VM을 사용하여 기본 인스턴스의 성능을 테스트할 수 있습니다.
확장 서비스 등급은 여러 클라이언트 VM에 맞게 성능이 최적화되어 있고 단일 클라이언트는 일반적으로 최대 클러스터 IOPS 또는 처리량을 달성할 수 없으므로 단일 클라이언트 VM을 사용하여 지역, 영역 또는 엔터프라이즈 인스턴스를 테스트하는 것은 권장하지 않습니다.

For detailed instructions and mounting options, see [Mounting file shares on Compute Engine clients](/filestore/docs/mounting-fileshares).\n\nMake sure to specify the [`nconnect`](https://man7.org/linux/man-pages/man5/nfs.5.html) mount option for increased NFS performance. For specific service tiers, we recommend specifying the following number of connections between the client and server:\n\nYou can optimize the NFS read throughput by adjusting the `read_ahead_kb` parameter value. For more information, see [Optimize the NFS read throughput with `read_ahead_kb` parameter](/filestore/docs/performance#read-ahead-kb).\n\nTest performance with a single client VM\n----------------------------------------\n\nUse the following scenarios to perform tests on basic instances. You can run the commands directly from your command line.\n\n- Maximum write throughput for basic instances smaller than 1 TiB:\n\n fio --ioengine=libaio --filesize=4G --ramp_time=2s\n --runtime=5m --numjobs=16 --direct=1 --verify=0 --randrepeat=0\n --group_reporting --directory=/mnt/nfs\n --name=write --blocksize=1m --iodepth=64 --readwrite=write\n\n- Maximum read throughput:\n\n fio --ioengine=libaio --filesize=32G --ramp_time=2s \\\n --runtime=5m --numjobs=16 --direct=1 --verify=0 --randrepeat=0 \\\n --group_reporting --directory=/mnt/nfs --buffer_compress_percentage=50 \\\n --name=read --blocksize=1m --iodepth=64 --readwrite=read\n\n- Maximum write throughput:\n\n fio --ioengine=libaio --filesize=32G --ramp_time=2s \\\n --runtime=5m --numjobs=16 --direct=1 --verify=0 --randrepeat=0 \\\n --group_reporting --directory=/mnt/nfs --buffer_compress_percentage=50 \\\n --name=write --blocksize=1m --iodepth=64 --readwrite=write\n\n- Maximum read IOPS:\n\n fio --ioengine=libaio --filesize=32G --ramp_time=2s \\\n --runtime=5m --numjobs=16 --direct=1 --verify=0 --randrepeat=0 \\\n --group_reporting --directory=/mnt/nfs --buffer_compress_percentage=50 \\\n --name=randread --blocksize=4k --iodepth=256 --readwrite=randread\n\n- Maximum write IOPS:\n\n fio --ioengine=libaio --filesize=32G --ramp_time=2s \\\n --runtime=5m --numjobs=16 --direct=1 --verify=0 --randrepeat=0 \\\n --group_reporting --directory=/mnt/nfs --buffer_compress_percentage=50 \\\n --name=randwrite --blocksize=4k --iodepth=256 --readwrite=randwrite\n\nTest performance with multiple client VMs\n-----------------------------------------\n\nTo achieve the maximum performance for zonal, regional, and enterprise instances, use multiple client VMs.\n\nWe recommend using eight client VMs per 1 TiB for instances between 1 and 9.75 TiB. For instances between 10 and 100 TiB use eight client VMs per 10 TiB.\n\n1. Start the fio server on all client VMs. Fio uses port `8765` to communicate, so this port must be open in your firewall policy.\n\n fio --server\n\n2. Select one client VM that will orchestrate the fio run. Create a [fio job file](https://fio.readthedocs.io/en/latest/fio_doc.html#job-file-format) on that client VM:\n\n cat \u003c\u003c EOL \u003e /tmp/fio_job.conf\n [global]\n ioengine=libaio\n ramp_time=2s\n runtime=3m\n time_based\n direct=1\n verify=0\n randrepeat=0\n group_reporting\n buffer_compress_percentage=50\n directory=\\${TMP_DIR}\n create_only=\\${CREATE_ONLY}\n\n [read-throughput]\n blocksize=1048576\n numjobs=8\n readwrite=read\n filesize=100M\n\n [write-throughput]\n blocksize=1048576\n numjobs=8\n readwrite=write\n filesize=100M\n\n [read-iops]\n blocksize=4k\n iodepth=64\n readwrite=randread\n filesize=1GB\n\n [write-iops]\n blocksize=4k\n iodepth=64\n readwrite=randwrite\n filesize=1GB\n\n EOL\n\n3. Create a `hosts.list` file that contains the IP addresses or DNS names of the fio client VMs:\n\n cat \u003c\u003c EOL \u003e /tmp/hosts.list\n \u003cClient 1 IP/DNS\u003e\n \u003cClient 2 IP/DNS\u003e\n ...\n \u003cClient N IP/DNS\u003e\n EOL\n\n4. Create the following dataset in a temporary directory on the client VM you created the job file for:\n\n export TMP_DIR=$(mktemp -d \u003cvar translate=\"no\"\u003eMOUNT_POINT_DIRECTORY\u003c/var\u003e/XXXXX)\n chmod 777 ${TMP_DIR}\n export CREATE_ONLY=1\n fio --client=/tmp/hosts.list \\\n --section=read-throughput --section=read-iops /tmp/fio_job.conf\n\n5. Run benchmarks using the client VM you created the job file for:\n\n - Maximum read throughput\n\n export CREATE_ONLY=0\n fio --client=/tmp/hosts.list --section=read-throughput /tmp/fio_job.conf\n\n - Maximum write throughput\n\n export CREATE_ONLY=0\n fio --client=/tmp/hosts.list --section=write-throughput /tmp/fio_job.conf\n\n - Maximum read IOPS\n\n export CREATE_ONLY=0\n fio --client=/tmp/hosts.list --section=read-iops /tmp/fio_job.conf\n\n - Maximum write IOPS\n\n export CREATE_ONLY=0\n fio --client=/tmp/hosts.list --section=write-iops /tmp/fio_job.conf\n\n6. After you are done with testing, stop fio servers on all client VMs and delete their\n temporary directory:\n\n rm -rf ${TMP_DIR}"]]
