ado.net - Accessing SQL Server in parallel -

-

i'm trying use task-parallel-library offload expensive ado.net database access ui thread (formerly program i'm re-writing freeze, updating vb6 text box progress, until data in database loaded). have complex dependency structure (26 individual tasks), , i'm trying figure out how of worth parallelizing.

i'd know whether or not io access can parallelized @ performance bonuses. if not i'll sequentially load data , update ui whenever enough information loaded perform task, it'd nice boost loading maybe 2 things @ time instead of 1 (even if don't double speedup).

it's possible parallelizing increase performance, not guaranteed. depends on bottleneck is.

for example, if request expensive because loads lots of data, consumes of clients network bandwith. parallelizing in case wouldn't much, if @ all.

if, on other hand, bottleneck sql processing and sql request leaves sql server spare capacity in own bottleneck, can profit sql servers (very good) parallelizing capabilities.

it possible parallelizing slows down. if example sql server has not ram , access single disk, forcing multiple queries in parallel may lead more seek activity on harddisk, can dramatically slow down overall read rate.

so, is, answer isn't simple yes or no, "it depends".

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
