>that wasn't always the case. i remember times where pv could be faster on a lot of forks 32bit, or 64bit pre-virtualization hardware extension (vt-x/d, ept, amd equivalents) are really the only ways this should have been the case. Each time you make a fork() system call on 64bit PV you're making an extra context switch and flushing the TLB that an HVM instance does not need |
