Hello everyone,=0D=0A=0D=0A=0D=0A=0D=0AI have a strange problem that I ha=
ve been trying to solve for months.=20=0D=0A=0D=0A=0D=0A=0D=0AA client ha=
ve a setup of 6-7 LTSP terminals and one server. Because of room structur=
e we need to have 3 switches, all are 1 GB. Server has one 1GB network ca=
rd. As I couldn't get LTSP working on CentOS 7 I switched to Ubuntu.=20=0D=
=0A=0D=0A=0D=0A=0D=0AProblem is the slowness of the clients. If 1-2 are w=
orking everything is fine, but when we have like 5 working the same time =
we get slowness, like when writing an email in Thunderbird it just stops =
showing the writing on the screen.=20=0D=0A=0D=0A=0D=0A=0D=0AI swtich awa=
y from KDE to LightDM (I think was the name), still same.=20=0D=0A=0D=0A=0D=
=0A=0D=0AOne thing we think might be the problem is the filemanager. When=
 somebody open filemanager and looks at the folder with like 100 files ev=
erything stop. All files are on the same server as LTSP is running.=20=0D=
=0A=0D=0A=0D=0A=0D=0AAny ideas where to look for the problem and solving =
it.=20=0D=0A=0D=0A=0D=0A=0D=0A=0D=0A=0D=0AKenneth=0D=0A=0D=0A=0D=0A=0D=0A=
