| |
Can some of you help us by doing such things as replicating our benchmarks, and helping us debug it as we enter the last stretch before Halloween?
Nikita and Oleg will describe the details of what to do to replicate the benchmarks, please be sure to use reiser4 readdir order for writes to reiser4 (that means don't use tarballs made from ext2 (Remember that writes determine subsequent read performance.)), and to use the latest hard drives and fast processors with udma 5 turned on. We are quite sensitive to transfer speed since we do a good job of avoiding seeks. We are sensitive to readdir order because we sort directory entries (which is necessary for having efficient large directory lookups). In reiser4.1 we will ship a repacker, and then it won't matter what order you do writes in so long as the repacker gets a chance to run at night.
