Well, it seems that my machine must just hate me, because I can't seem to get them to work for more than a few minutes. Been having lots of bad luck lately though.. oh well. :( Anyways, I do have a few comments.. I have gotten the following panic many times. It seems to occur even when I do not have soft updates turned on for any of my file systems. :/ panic: softdep_disk_io_initiation: read >From looking at the code, this seems to indicate that dependancies are being formed for read operations as well. This seems somewhat disturbing.. any ideas? >look in: >ftp://ftp.freebsd.org/pub/FreeBSD/incoming/softupdates4.tgz > >first extract the README and read it before extracting everything. >this should patch cleanly against last night's -current. In the readme, you might want to mention running 'make includes' or something before building the userland programs. If you don't, some of the defines are not defined. :) >try a make world before and after.. >particularly, >make /var/tmp and/or /usr/obj use softupdates. > >for a real laugh, try timing deletion of a large directory hierarchy.. I was curious about this.. when i rm'd my /usr/obj, it took about 30 seconds or so. This seems like a while to me.. I guess maybe I am impatient though. ;) Although it seemed faster in OpenBSD, i can't accurately compare due to possible caching effects. (in FreeBSD, the tree was completely untouched beforhand--not recently untarred) Either way, I was curious about the sync/async stats given in mount. It seems that some operations are still being done sync?! Also, perhaps the stats should be an option to mount rather than given by default.. >enjoy.. > >courtesy of: >Kirk Mckusick >John Dyson, >Whistle Communications. (Julian Terry and Archie) Thanks much to all involved. :) I have been looking forward to seeing this work done and integrated for while now. >this at least should put an end to the >"ext2fs is faster" arguments, even if they are based on apple/oranges >comparisons. :-) I can't wait. :) It's rediculous, but still annoying to keep hearing this one.
