Hi Frank, I tried both 2.6 and 2.5-stable. 2.6 showed marginal improvements
at-least for my workload (improvement of ~1K for 70% read, 30% random workload).

What version are you running? Significant improvements have been made in V2.6
(which is close to being tagged V2.6.0).

Subject: [Nfs-ganesha-devel] nfs ganesha vs nfs kernel performance
Hey Guys,
I ran few performance tests to compare nfs gansha and nfs kernel server and
noticed significant difference.
Please find my test result:
SSD formated with EXT3 exported using nfs ganesha : ~18K IOPS Avg latency:
~8ms Throughput: ~60MBPS
same directory exported using nfs kernel server: ~75K IOPS Avg
latency: ~0.8ms Throughput: ~300MBPS
nfs kernel and nfs ganesha both of them are configured with 128 worker threads.
nfs ganesha is configured with VFS FSAL.
Am I missing something major in nfs ganesha config or this is expected behavior.
Appreciate any inputs as how the performance can be improved for nfs ganesha.
Please find following ganesha config file that I am using:
NFS_Core_Param
{
Nb_Worker = 128 ;
}
EXPORT
{
# Export Id (mandatory, each EXPORT must have a unique Export_Id)
Export_Id = 77;
# Exported path (mandatory)
Path = /host/test;
Protocols = 3;
# Pseudo Path (required for NFS v4)
Pseudo = /host/test;
# Required for access (default is None)
# Could use CLIENT blocks instead
Access_Type = RW;
# Exporting FSAL
FSAL {
Name = VFS;
}
CLIENT
{
Clients = *;
Squash = None;
Access_Type = RW;
}
}
Thanks & Regards,
Deepak
