Operating Systems Solaris Solaris 11.1 Slow Network Performance Post 302826013 by Just Ice on Tuesday 25th of June 2013 04:10:22 PM

you may be right about the loopback but i cannot say for sure as i do not have access to those kind of machines -- maybe somebody else here can explain further ...

you may also want to see the configurations of the appropriate network devices on your other solaris servers and their appropriate ports on the switch if they are able to send the big files much faster ...

btw, i had my network group actually hard set the affected ports on the switch to run 100/full so my servers' network ports were not continually auto-negotiating ... the standards at that company was also to set every network port to auto but they had to make an exception for my production servers ...

if your network group balks at the request to hard set the ports, call up oracle support to see if they have better ideas if nobody else here has one ...

NAME
aseqnet - ALSA sequencer connectors over network SYNOPSIS
aseqnet [remotehost] DESCRIPTION
aseqnet is an ALSA sequencer client which sends and receives event packets over network. Suppose two hosts connected by network, hostA as a server and hostB as a client. The ALSA sequencer system must be running on both hosts. For creating the server port, run the following on hostA: hostA% aseqnet sequencer opened: 128:0 Then a user client 128 with port 0 was opened on hostA. (The client number may vary.) For creating the (network-)client port, run aseqnet with the hostname of the server: hostB% aseqnet hostA sequencer opened: 132:0 Now all events sent to hostA:128:0 are transferred to hostB:132:0, and vice versa. The ports created by aseqnet can be connected arbitrary to other sequencer ports via aconnect(1). For example, to connect hostB:132:0 to a MIDI output device 65:0: hostB% aconnect 132:0 65:0 Then events to hostA:128:0 will be delivered to hostB:65:0. The following command plays MIDI on hostB. hostA% pmidi -p 128:0 foo.mid The multiple clients may exist simultaneously. If hostC is connected as a client to hostA, events from from hostA are sent to all con- nected network clients, i.e. hostB and hostC. However, only one connection is allowed from a client to a server. To disconnect network, stop all clients before server by ctrl-C or sending signal to them. The server will automatically quit. OPTIONS
-p port Specify the TCP port number or TCP service name. -s addr Subscribe to the given address for read automatically. -d addr Subscribe to the given address for write automatically. -v Verbose mode. SEE ALSO
