Subject [jira] [Commented] (CXF-6189) Improve memory usage of UrlUtils
Date Tue, 13 Jan 2015 12:14:34 GMT


Sergey Beryozkin commented on CXF-6189:

Hi, applied your patch with minor modifications, have a look please.
I think we may still optimize it a little bit; can you give me a favor and experiment with
what is faster for values which have no % characters:
effectively do a copy as we do now or check if '%' is there and if not then just return String.
Perhaps it is obvious the 2nd option is faster, though it would make it a bit slower to decode
%-encoded values, but given that it is 80% case for non-encoded values then may be we should
do a check after all, at least for Path parameters...

> When I run load test, I find that the management of encoding parameters of the urls is
consumer memory.
> I do not know if it is possible to optimize this part.
> Throughput of load test : 400 query/s
> ~80% GET query with 6 parameters
> ~20% POST query with 6 parameters GET and 1 payload
