I'm getting 5s from cold start to return from ''BrowserStartup'' (JavaScript), e.g. | |||
<pre> | |||
./d firefox-bin startup.d stop-js.d | |||
dtrace -Zqw -x dynvarsize=64m -x evaltime=preinit -p 55752 -s startup.d -s stop-js.d -s sigcont.d | |||
kill -CONT 55752 | |||
Total: 5000.294085ms | |||
</pre> | |||
The hot path for those 5s looks like this: | |||
<pre> | |||
./d firefox-bin hotpath.d stop-js.d | |||
dtrace -Zqw -x dynvarsize=64m -x evaltime=preinit -p 55765 -s hotpath.d -s stop-js.d -s sigcont.d | |||
kill -CONT 55765 | |||
