The current state of vimage in -current is such that we can do some performance testing. Unfortunatly I don't have a test plan in place.. The aim is to run some tests on systems with VIMAGE_GLOBALS defined and not defined and see if there are any detectable differences. Firstly I have done some simple tests myself (e.g. scps, pings, ftps) but it would be very helpful if people coudl compile up an alternative kernel with VIMAGE_GLOBALS defined and see if their everyday workloads show any noticeable differences. nothing special.. just time a few things you often do that may be special to you and are network intensive, and then switch to the other kernel and try it again. Then put the results in ministat (saying whether bigger is better or worse) Ok do it several times for statistical purposes, reply to me (and the list) and let us know if you are seeing differences anywhere.. regards.. Julian (p.s. I will put numbers up too when I get some more)
