Thanks Adrien for reply.
My script filter was,
{
"script": {
"script": "xyz",
"params": {
"startRange": 1407939675, // Timestamp in
milliseconds ... keep changing on all queries
"endRange": 1410531675 // Timestamp in
milliseconds..... keep changing on all queries
},
"lang": "native",
"_cache": true // I removed this caching and i
found significant performance improvement... do you know why ? 
}
},
===============================================================================================
My Native(Java) script code // Return true if date ranges overlaps.
===========================================================================
ScriptDocValues XsDocValue = (ScriptDocValues) doc().get(
"start_time");
long XsLong = 0l;
if (XsDocValue != null && !XsDocValue.isEmpty()) {
XsLong = ((ScriptDocValues.Longs) doc().get("start_time"))
.getValue();
}
ScriptDocValues XeDocValue = (ScriptDocValues) doc().get("end_time");
long XeLong = 0l;
if (XeDocValue != null && !XeDocValue.isEmpty()) {
XeLong = ((ScriptDocValues.Longs) doc().get("end_time"))
.getValue();
}
if ((endRange >= XsLong) && (startRange <= XeLong)) {
return true;
}
===========================

Script filters are inherently slow due to the fact that they cannot
leverage the inverted index in order to skip efficiently over non-matching
documents. Even if they were written in assembly, this would likely still
be slow.
What kind of filtering are you trying to do with scripts?

How to access field data faster from native (java) script ??? should i
enable 'doc values'?
I am already using doc().getField() and casting to long. It is date field
type. But whenever, my argument to script changes, it has poor performance
for search query. Subsequent call with same argument has good performance.
(might be because _cache is true for that script filter.)
Thanks.
