Chapter 3 Analyzing NFS Performance. This chapter explains how to analyze NFS performance and describes the general steps for tuning your system. This chapter also describes how to verify the performance of the network, server, and each client. Tuning the NFS Server. When you first set up the NFS server, you need to tune it for optimal performance.
NFS Performance Goals . Rotating SATA and SAS disks can provide I/O of about 1 Gbps. Solid-state disks can fill the 6 Gbps bandwidth of a SATA 3 controller. NFS should be about this fast, filling a 1 Gbps LAN. NFS SAN appliances can fill a 10 Gbps LAN. Random I/O performance should be good, about 100 transactions per second per spindle.

08.07.2014 · ESXi 5.x NFS IOPS Limit Bug – Latency and Performance Hit. There is another NFS bug hidden in the latest ESXi 5.x releases…while not as severe as the 5.5 Update 1 NFS Bug it’s been the cause of increased Virtual Disk Latency and Overall Poor VM performance across a couple of the environments I manage. The VMwareKB Article referencing the ...
23.09.2021 · Predictable performance and cost that scales with capacity. Extremely low latency (as low as sub-ms). Rich NetApp ONTAP management capability such as SnapMirror in cloud. Consistent hybrid cloud experience. Performance (Per volume) Up to 20,000 IOPS, up to 100 Gib/s throughput. Up to 100,000 IOPS, up to 80 Gib/s throughput.
We plan to use these servers as Splunk indexer but - since Splunk does not suggest NFS as storage - we wanted to do some performance tests before. So I ran ...
04.01.2022 · The following is the output of nfsiostat. We can get the NFS performance metrics here like NFS IOPS, bandwidth, latency. op/s This is the number of operations per second. rpc bklog This is the length of the backlog queue. kB/s This is the number of kB written/read per second. kB/op This is the number of kB written/read per each operation. retrans
15.12.2021 · You can now get started using NFS by following these simple step-by-step instructions. See the documentation for more information. Improved performance. Today, we are announcing more IOPS and throughput for all premium file shares (SMB and NFS). All shares now provide a minimum of 3000 IOPS, up from the previous 400 IOPS baseline.
This test should be run both on the NFS server and on the application nodes ... [100.0% done] [131.4MB/44868KB/0KB /s] [33.7K/11.3K/0 iops] [eta 00m:00s] ...
02.12.2008 · Reaching 145,000 4+ Kbyte NFS cached read ops/sec without blowing out latency is a great result, and it's the latency that really matters (and from latency comes IOPS). On the topic of latency and IOPS, I do need to post a follow up for the next level after DRAM: no, not disks, it's the L2ARC using SSDs in the Hybrid Storage Pool.
