But I > wonder if that worth the price difference. I do not have LX2K experience, but . . . An illustration of the type of question: I have access to both a MACCHIATObin DoubleShot (A72 based) and a OverDrive 1000 (A57 based). Turns out the OverDrive 1000 is faster at parallel builds overall vs. the MACCHIATObin being so for single-threaded activity. The OverDrive 1000 has dual channel memory. Both are configured to have SATA SSDs of the same type and the I/O does not seem to contribute differently for builds. (The file system context is UFS for both.) As an example (from memory), a poudriere bulk build session set up to do the same on both got results like: OverDrive 1000: 15 hours MACCHIATObin DoubleShot: 18 hours (in round figures). The poudriere configurations for both allowed 4 jobs at once, each job allowed to use 4 processes per job. (So much of the time the load average was more than 4.) For both there was enough RAM that the builds avoided swapping/paging, if I remember right. Sounds like a LX2K would be an interesting thing to compare with. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
