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= --=_IcfbRSc4koiccIKKk3mDdV+fY47kBExezcDymXfzreFHukan Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://ww= w.w3.org/TR/html4/loose.dtd"><html>=0A<head>=0A <meta name=3D"Generator"= content=3D"Zarafa WebApp v7.1.11-46050">=0A <meta http-equiv=3D"Content= -Type" content=3D"text/html; charset=3Dutf-8">=0A <title>LTSP slowness p= roblem</title>=0A</head>=0A<body>=0A<p style=3D"padding: 0; margin: 0;"><= span style=3D"font-family: tahoma; font-size: 10pt;">Hello everyone,<br /= ></span></p>=0A<p style=3D"padding: 0; margin: 0;"><span style=3D"font-fa= mily: tahoma; font-size: 10pt;"><br /></span></p>=0A<p style=3D"padding: = 0; margin: 0;"><span style=3D"font-family: tahoma; font-size: 10pt;">I ha= ve a strange problem that I have been trying to solve for months. <br /><= /span></p>=0A<p style=3D"padding: 0; margin: 0;"><span style=3D"font-fami= ly: tahoma; font-size: 10pt;"><br /></span></p>=0A<p style=3D"padding: 0;= margin: 0;"><span style=3D"font-family: tahoma; font-size: 10pt;">A clie= nt have a setup of 6-7 LTSP terminals and one server.
