Not to pick an argument, but a lot of the complaints about HT were from a long time ago, even though I still encounter people who insist that it has to be shut off.
Also, up-to-date releases of PHP and every other framework should be able to handle modern hardware.
Again, not to argue, FRiend.
No argument. I could be “wronger” than a 13 year old male prostitute discovered in a hotel room with your preacher. Why I think it is threading. Setting to 20 fixes it. FR is legacy code. FR used to be magnificently fast. HT had lots of OS issues. Older compilers have no idea of the multicore nature of todays CPUs even run time ones. The repeatability at a point of time of the failure and that it is not consistent over time. Have seen it over and over again. IMHO it is a problem with FR running on a multicore system. Best fix IMHO is run FR in a vm emulating a single core system and let the OS and VM handle the switching.
