Performance is slow when writing to USB storage devices attached to the device.
IGEL Linux v4 before 4.14.100 and IGEL Linux v5 before 5.06.100:
By default the device's system synchronizes the process of writing to USB with the progress status visible for the user. This may slow down the writing process a little bit but on the other hand makes writing to removable devices more reliable.
To speed up writing on USB media, it is possible to deactivate the parameter sync_option.
- Go to IGEL Setup > System > Registry > devices > autofs > sync_option.
- Disable sync_option.This setting will not speed up USB performance for USB Redirection mode such as Vmware Horizon View, Citrix XenDesktop, Fabulatech or Microsoft RemoteFX.
With IGEL Linux 4.14.100 / 5.06.100 the default setting has changed to sync_option = disabled. A new parameter has been added: devices.autofs.flush_option (default enabled) to allow a safe writing process with significantly higher performance. Enable sync_option to get back to the previous behavior.
