See my other posting to this list. It works fine. |

That was the thread-safe problem with threaded Apache2 MPMs (such as |
| 8 |
worker). Again, see my other post about it. 6 months ago, there were a |
| 9 |
lot more thread-safe extensions in PHP, since then the great majority |
| 10 |
have been fixed. Just net-snmp and mcrypt still, and those have fixes in |
| 11 |
them AFAIK but I don't know if the PHP people have looked if the fixes |
| 12 |
are good enough. |

I did a little quick testing at work. All values are approximate, |
| 19 |
rounded DOWN to the nearest multiple of 10. These tests are a very |
| 20 |
simple little script I cooked up, and should not be taken as any |
| 21 |
definite performance guide. The actual speed measurements were taken |
| 22 |
with 'ab2', on a seperate machine, running over gigabit ethernet. |
| 23 |
The test server is a dual Xeon 2.66Ghz, 1GB ECC RAM. Pages are served |
| 24 |
from a ramdisk. |

Apache1+PHP vs. Apache2(prefork MPM [default])+PHP = dead heat, |
| 27 |
different hardware setup might push it in either direction. This is a |
| 28 |
non-threaded MPM, so no threadsafe issues here. |
| 29 |
|
| 30 |
All of the remaining MPMs below are threaded: |
| 31 |
|
| 32 |
Apache1+PHP vs. Apache2(worker MPM)+PHP = Apache2 pushes out ~10% more |
| 33 |
pages than Apache1. |
| 34 |
|
| 35 |
Apache1+PHP vs. Apache2(perchild MPM)+PHP = Apache1 wins by ~10%, but |
| 36 |
this MPM is intended for more security, not performance. |
| 37 |
|
| 38 |
Apache1+PHP vs. Apache2(leader MPM)+PHP = Apache2 wins by ~20%, but this |
| 39 |
MPM seems unstable over longer periods (and it _is_ marked in the |
| 40 |
Apache2 docs as such). |
