SSIS- OleDb Fast Load vs. Bulk Insert Task -

-

i have done research including threads on forum cant seem find answer.

i loading text files 40 columns. no transformation @ time. there 8 files ~25mb total of 1,400,000 rows. using bulk insert task load completes in 3 minutes. using oledb destination , flat file input connection manager load completes in 30 minutes.

from have read, ssis should using bulk inserts behind oledb connection. if so, why there such dramatic difference? must doing wrong, ideas?

using defaults connection. table or view fast load. blank rows per batch , max commit size 2,147,483,674. using sql2016 have had similar results testing sql2014.

you might not setting properties of data flow task such defaultbuffersize , defaultbuffermaxrows.

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...
