Espruino speed improvements - compiled JavaScript?

The problem never went away on my computer.
Its running windows 8.1 64bit, 4 cores, 8gb ram, connected over USB.

• tried to give it more time for reading(up to 10 secs), did not help.
  
• added timeout in env.js before calling core.utils.execute Expr.., did not help
  
• reading process.env from terminalwindow always works fine
  
  

In log I see, process.env-object stops somewhere in exports, like this
No result found - just got "echo(0);\r\n<<<<<{\"VERSION\":\"1v72\",­\"BUILD_DATE\":\"Dec 24 2014\",\"BUILD_TIME\":\"12:10:46\",\"GIT­_COMMIT\":\"cca740699928e7f5ee1cee62e432­99e19b33f10f\",\"BOARD\":\"ESPRUINOBOARD­\",\"CHIP\":\"STM32F103RCT6\",\"CHIP_FAM­ILY\":\"STM32F1\",\"FLASH\":262144,\"RAM­\":49152,\"SERIAL\":\"33ffd905-41573033-­07710743\",\"CONSOLE\":\"USB\",\"EXPORT\­":[\"jsvLock,jsvLockAgain,jsvUnLock,jsvM­athsOp,jsvMathsOpSkipNames,jsvNewFromFlo­at,jsvNewFromInteger,jsvNewFromString,js­vNewFromBool,jsvGetFloat,jsvGetInteger,j­svGetBool,jspeiFindInScopes,jspReplaceW"­
