i trying python based web scraping execution time pretty critical. i've tried phantomjs, selenium, , pyqt4 now, , 3 libraries have given me similar response times. i'd post example code, problem affects three, believe problem either lies in shared dependency or outside of code. @ around 50 concurrent requests, see huge desegregation in response time. takes 40 seconds 50 pages, , time gets exponentially slower greater page demands. ideally i'm looking ~200+ requests in 10 seconds. used multiprocessing spawn each instance of phantonjs/pyqt4/selenium, each url request gets it's own instance i'm not blocked single threading. i don't believe it's hardware bottleneck, it's running on 32 dedicated cpu cores, totaling 64 threads, , cpu usage doesn't typically spike on 10-12%. bandwidth sits reasonably comfortably @ around 40-50% of total throughput. i've read gil, believe i've addressed using multiprocessing. webscraping inherently slow thi...

i confused if 'vary traits' right thing define different set of layout constraints portrait & landscape mode on iphone. objective have different layouts portrait & landscape modes on iphone (doesn't matter on ipad). tried 'vary traits' , define different set of nslayoutconstraints portrait & landscape modes seems not working. if have constraints p1 & p2 active portrait mode , c1 & c2 landscape mode same view, should job. 'vary traits' meant job? also how undo variations might have added using 'vary traits'? you need following - set constraint in portrait mode. select landscape mode. disable constraints set in portrait mode. assign new constraints landscape. go in portrait mode , disable constraints set in landscape mode. that's it. hope works. feel free comment if have confusion..
