So, I modified the patch to defer proc_create() with taskqueue(9). Below is `time make -j5 buildkernel WITHOUT_MODULES=yes` perf. evaluation. Done on 4-way CPU on clean /usr/obj with /usr/src & /usr/obj both nfs-mounted over 1Gbit LAN. clean old 1137.985u 239.411s 7:42.15 298.0% 6538+2133k 87+43388io 226pf+0w clean new 1134.755u 240.032s 7:41.25 298.0% 6553+2133k 87+43367io 224pf+0w Patch needs polishing, though it generally works. Not sure if shep_chan (or whatever name it will get) needs locking. -- wbr, pluknet
