as java doc explains as general rule, default load factor (.75) offers tradeoff between time , space costs. higher values decrease space overhead increase lookup cost (reflected in of operations of hashmap class, including , put). i not getting how increasing load factor 1, increase lookup time for example:- initial capacity 16 , load factor 1 resizing 32 happen after size reaches 16 * 1 = 16. if put new new entry how lookup time more in comparison if load factor have been .75 (in case hashmap have resized @ size 2 ) as answer says what significance of load factor in hashmap? lesser number of free buckets ,higher chances of collision. i not sure how number of free buckets related chance of collision. per mine understanding, bucket decided based on hashcode of key object. if comes out same key object in bucket there chances of collision otherwise go different bucket (out of availablke bucket ). how come collision related free buckets ? mean if hashcode differen...

i author of r package ( clustermq 0 ) distributes function calls on hpc schedulers using using zeromq bindings ( rzmq ). have used simple combination of req / rep sockets, workers requesting first common data tasks (the function call , constant arguments), , data each call should evaluate master. worked far, because running computations order of magnitude slower sending , receiving data. one issue common data can have several hundred mb in size, while iterated data small. can happen master busy sending huge chunk of common data , can not send iterated data @ same time. because of this, there noticeable delay when starting distributed computation. however, may not caused actual sending rather preparing message. documentation states: zeromq not send message (single or multipart) right away, @ indeterminate later time. so i'm wondering: is zeromq sending out data put in queue send() 1 after other or in parallel? 1 make difference or negligible? there way influen...
