Hi Mark, Is it possible that you used to have coot set up to use the slow computer settings and now you don't.
Try adding the slow computer configuration settings to your .coot file. Information can be found at: http://www.ysbl.york.ac.uk/~emsley/coot/doc/chapters/user-manual_8.html#SEC2 02 Good luck, Eric __________________________ Eric Larson, PhD MSGPP Consortium Department of Biochemistry Box 357742 University of Washington Seattle, WA 98195 On Thu, 4 Feb 2010, Mark A.

Hello, Does anyone know why COOT is suddenly as slow as molasses on my Fedora 12 desktop? I had and old version of Coot working after my initial Fedora 12 install (from FC7 after a disk crash). However, now all versions of COOT have the same problem, very slow response and refresh rates. It does not seem to matter whether the directory is local or NFS, even before a PDB file is loaded it slows to a crawl. With a PDB file loaded the interface becomes catatonic. Centering takes several seconds. Any idea what the problem could be? COOT was amazingly fast on the same hardware with FC7, so it must be Fedora12 specific. The glxgears speed seems slow to me. # COOT 0.6.1 coot-Linux-i386-fedora-10-gtk2-python/ coot-Linux-i386-fedora-12-gtk2/ coot-Linux-i386-fedora-4-gtk2/ COOT 0.4.1 coot-Linux-i386-fedora-5 # Hardware TYAN S2865A Tomcat K8E Dual Core AMD Opteron 2.4GHz 2 GB RAM ATI Radeon RV530 (Radeon X1600pro) kernel-PAE-2.6.31.12-174.2.3.fc12.i686 xorg-x11-server-Xorg-1.7.4-1.fc12.i686 # glxgears 8071 frames in 5.0 seconds = 1614.093 FPS 8105 frames in 5.0 seconds = 1620.857 FPS Yours sincerely, Mark A.
