Are any of you running hardware with odd or sub-par disk IO?
I've been in contact with a fellow who reports 2-3sec per package in --not mode, and similar results for revdep'n a single package. Seems it is because his hard drive controller chipset is integrated with CPU.
If anyone else experiences delays such as this, I'd love to hear.
For lsneeds python, I get about 0.047sec, with 19 packages depending on python.
I personally get about 21sec for a --not operation, with about 800 packages installed. That averages out to 0.03sec per package if my math doesn't fail me.
I'm considering implementing a pre-loader option for --not, that copies the ~3mb package_data file to a ramdisk. Seems vector implements ramdisks in 15mb chunks, but I don't know if this is "growing" or static size. This would of course require that lsneeds be ran as root, or that a sudo command be setup for ramdisk instantiation.
