Why shouldn't you always use Apache's event MPM instead of the worker MPM? -


mpm_event mpm_worker except mpm_event manages (non-ssl) keepalive connections separate, dedicated thread rather having each thread manage each individual connection. giving , keeping dedicated thread each keepalive connection, mpm_worker leaves thread , resources bound connection regardless of whether or not request being processed. mpm_event on other hand, can lower system resource use in high concurrency environments allowing thread , resources recycled system once requests complete.

it seems me in high concurrency, non-ssl environments keepalive has long timeouts, mpm_event has potential make system can handle higher workload equivalent resources system same resorces using mpm_worker. more importantly, seems me in terms of resource use , features, mpm_event @ least mpm_worker, if not better, in circumstances.

despite understanding mpm_event @ least , possibly better, favorite linux distributions default using mpm_worker when installing apache 2.4 repositories. makes me wonder if thinking incomplete , if there technical reason missing use mpm_worker rather mpm_event in apache 2.4.

my question therefore correct in saying mpm_worker @ least mpm_event, if not better, in circumstances, , (2) if not, technical benefits there using mpm_worker in apache 2.4?

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
