Subject Re: reuse cached files
Date Mon, 02 Aug 2010 13:27:57 GMT
I am actually doing some test to see the performance. I want to eliminate the 
interference of distributed cache. I find there is method in the api to purge 
the cache. That might be what I want.

I may be able to answer this better if I understand the use case. If
you need the same files for every job, why would you need to send them
afresh each time ? If something is cached, it can be reused, no ? I am
sure I must be missing something in your requirement ...
