The bechmarks of my machine compared to machine XXX / OS YYY look way apart. Why is this?
When the BOINC client is first run on a machine, it does some testing to determine how fast that machine does floating point and integer mathematical operations. Some versions of the BOINC client do not make this determination very accurately, either over- or under-reporting the performance of the machine. In particular, on Windows machines, the MS compilers optimized away some of the benchmark tests, making the machines appear faster than they were. The opposite effect also arises on Macs and some 64-bit Linux machines, where the BOINC client would show better performance if it were compiled with additional optimization switches. [BA] The downloads of the Workunits are quite large / too large for modem users. The Einstein@Home workunits require a large data file (slightly more than 12 MB in size). With a 57.6kb modem, this file will take close to an hour to download. Once you have downloaded it, the Einstein@Home scheduler should send you a number of workunits for that file, so you wo
