1.
Is there any known and confirmed performance issue when installing these latest SLES fixes:
[LIST]
[_]SUSE-SLE-SERVER-12-SP3-2018-1573
[_]SUSE-SLE-SERVER-12-SP3-2018-1656
[\*]
[/LIST]
1.
In case there is an essential performance issue, can I skip these fixes permanently when the SLES server are trusted - e.q. they are used only by our organization with no 3rd party software except standard programs/services like Apache, PHP, NFS, MySQL? But not Samba!
If they can be skip them is there a way to remove them from the update list?
