- Configure Yocto Project*/Wind River* Linux* and Intel® VTune™ Profiler with the Intel System Studio Integration Layer
Problem: VTune Profiler is Slow on X-Servers with SSH Connection
Intel® VTune™ Profiler GUI may respond slowly when you run a remote Linux* collection using an X11-forwarding/X-server.
The GUI response may be slow if you use an X-server (for example, Xming*) with SSH on Windows to run the VTune Profiler GUI on a connected Linux machine and the X-server is slow.
Option 1: Enable Traffic Compression
Compression may help if you are forwarding X sessions on a dial-up or slow network. Turn on the compression with ssh -C or specify Compression yes in your configuration file.
SSH obtains configuration data in the following order:
ssh -C command-line option
user configuration file (~/.ssh/config)
system configuration file (/etc/ssh/ssh_config)
You can explore all available options with man ssh_config.
Option 2: Change Your Encryption Cipher
The default cipher on many systems is triple DES (3DES), which is slower than Blowfish and AES. New versions of OpenSSH default to Blowfish. You can change the cipher to Blowfish with ssh -c blowfish.
Change your configuration file with the Cipher option depending on whether you are connecting with SSH1 or SSH2:
for SSH1, use Cipher blowfish
for SSH2, use Ciphers blowfish-cbc,aes128-cbc,3des-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc
You may also follow recommendations provided in the documentation to an X-server you are using.
