Profiler server stores profiling results in a web folder.

[shibukawa]

Profiler server (make server) stores results in web folder.

If the user use in Linux or MacOS with MacPorts, this folder is not writable. I think the one of the following options should be selected:

• Store result in $HOME/.jsx folder (like .jsx/profile)
• Don't write profiling results to local storage. Store them in memory.
