search for: 2x10gb

Hi, I am looking for tools to migrate Mails from one IMAP-Server to another. Until now I have always used imapsync, but it seems very slow. Even over a 2x10GB/s connection I only get speeds of about 600KiB/s, because the programm always pauses betweeen every single mail. Does anyone here have a suggestion for an alternative? Thanks in advance Julian

So I don't think it's the client. The smbclient code is v...

Take a look at mbsync (isync). Very flexible and quite fast. I've also used offlineimap for a long time. DC

Setup:  Server 2x10GB NIC, client 1x1GB: Using smbclient with -mSMB3 I get an average of 52000 KiloBytes/sec (before 45000), using NFS (v3) from the same server I get  108000 KiloBytes/sec an more (mount ; cp; umount; ...)

The number of threads has nothing to do with the number of cores on the machine. It depends on the I/O, network speed, type of workload etc. We usually start with 32 threads and increase if necessary. You can check the statistics with: watch 'cat /proc/net/rpc/nfsd | grep th? Or you can check on the client nfsstat -rc Client rpc stats: calls retrans authrefrsh 1326777974 0

...ally careful when changing the setup of the servers. On a cluster node I try to set "rsize=1048576,wsize=1048576,vers=4,tcp" (I cannot have a larger value for rsize/wsize) but comparison with the mount using default setup do not show significant improvements. I sent 20GB to the server or 2x10GB (2 concurrent processes) with dd to be larger than the raid controller cache but lower than the? server and client RAM. It was just a short test this morning.

Hi, I'm looking for some recommendations for a "fast" fileserver regarding the hardware you use. We have different fileservers as our requirements changed over time. The "main" problem we are faced with is, that with smb (windows 7 and OS X) clients we never get really close to GBit speed on reads or writes. Using the same servers/storages with ftp, ssh, rsync, nfs we
