c# - Runtime.Caching.MemoryCache throws OutOfMemoryException when add many item to cache -


for heavy calculation want to put temp results memorycache , load again when required. when put 2 million object cache, throws outofmemoryexception.

i run program on windows 7 64 bit 8gb ram.

when task manager see application take 1.5 gb ram , crash. code similar in program

namevaluecollection config = new namevaluecollection {     {"cachememorylimitmegabytes", "4000"},     {"physicalmemorylimitpercentage", "100"} }; memorycache cache = new memorycache("mycache", config); cacheitempolicy policy = new cacheitempolicy { absoluteexpiration = objectcache.infiniteabsoluteexpiration }; (int = 0; < 4000000; i++) {     var resultoftempoperation = dooperation();     cacheitem newemployee = new cacheitem(guid.newguid().tostring(), new someclass());     cache.add(newemployee, policy); }

what wrong in code?

in visual studio go

solution>properties>configuration properties>platform

make sure compiling x64 if need use memory. (you hitting 32bit limit)

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
