It seems that there is a problem in the Windows Netware Client : When 1byte is sread, 512 are requested within the protocol. This looks like readahead (which is good), but when requesting the following byte, a new request is made (i.e the previous buffer was not cached). -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.freedesktop.org/show_bug.cgi?id=56007 --- Comment #1 from Mathieu Parent math.par...@gmail.com --- This problem is seen on a Novell Storage Services (NSS, or ncpfs on Linux). A network capture shows that file is read one byte at a time. Digging further, I found that shell/source/win32/shlxthandler/thumbviewer/thumbviewer.cxx load a ZipFile (line 360) and then call GetUncompressedContent on it. This call readCentralDirectoryEntry several times and readCentralDirectoryEnd. Those two fuctions use readByte which sread one char at a time ! -- You are receiving this mail because: You are the assignee for the bug. ___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs
