this makes YaCy search results VERY fast for all verify=false search cases and it enhances the search speed also for all other snippet-fetch cases. With this change my peer performed 100 Queries Per Second (!!!) while doing 10 queries simultanously (!!!) in an intranet index of 20000 URLs on my 16-core Mac Check this yourself by doing: cd bin ./searchtestmulti.sh after finishing the run, divide 1000 by the given time per query (which is the qps for one thread) and then multiply again by 10 (because 10 search threads has been started) git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7231 6c8d7289-2bf4-0310-a012-ef5d649a1542
