Hi, It would be great to know more about the performance of this LiteSpeed sapi. How does memory usage scale with # connections ? What is the performance under load, when compared to FPM sapi ? Are they both equal or is one faster than the other one? It would be especially nice to know because the php-team will probably not have enough resources to heko with both of these. Currently i have not seen any good performance comparison between fpm and Litespeed sapis. But you do something like the following command: # Stress test httperf --hog --server=127.0.0.1 --uri=/phpinfo.php --num-conns=200 --rate=100 --timeout=2 Varying the numbers will affect the duration and number of simultaineous connections.
