webserver - Does concatenation improves I/O performance? -

-

http/2 nice improvement, don't have network overhead related creating multiple connections download multiple files, , recommended stop concatenating js , css files improve caching, i'm not sure if perspective of i/o, having read multiple files hard drive impact performance.

i don't know if web servers apache or nginx have ram caching of frequent files , avoids i/o overhead , can stop concatenating , stop worrying this.

no, having read multiple files hard disk won't worsen performance, specially if using current crop of ssd hard-drives. have amazing performance , them network bandwidth, ssl , else bottlenecks.

also, operating systems automatically cache in ram accessed files, feature doesn't need built web server, because built operating system. , works if using magnetic drives.

there 1 thing though. (at shimmercat.com) have noticed compression suffers having multiple small files instead of concatenated one. in sense, have been nice if http/2 had included compression format sdch ... should matter more particularly small files big files. in all, think cache benefits small files worth it.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
