I mean up to 20secs waiting for some operations. That normally happeny when I do a svn up on a big subversion repository, but even on other locations. Yesterday a simple sync took 30sec although I was not doing anything else. I am *quite* sure that it wasn't like that in former kernel revisions, but I don't have old ones at hand for testing. Is there something known about a regression in this area? Sorry for not Cc-ing the right people, didn't know who it could be. Thanks a lot for any help/remarks/suggestions Norbert ------------------------------------------------------------------------------- Dr. Norbert Preining Associate Professor JAIST Japan Advanced Institute of Science and Technology preining@jaist.ac.jp Vienna University of Technology preining@logic.at Debian Developer (Debian TeX Task Force) preining@debian.org gpg DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------------- QUOYNESS (n.)
