Entity Framework Code First Performance and Memory Consumption -


in 1 of our environments, have built code generator power user can create models @ runtime , deploy them. no need mention using ef 5.0 code first.

our application has many models using internally. dbcontext may end having @ least 80 properties , more (80+ tables).

what observing initial asp.net application load time rather high , memory consumption in iis process high (600mb+).

what ways can configure ef more careful performance , memory usage?

update: seems way pre-compiled view generation fixed entities. way can boost performance since ratio of fixed models dynamic ones 60% 40% in our projects

how generate per-compiled views code-first?

update: using ef power tools able generate views. wondering if can have 2 separate code-first contexts in same project. 1 intend generate views since models fixed. second 1 models can changed administrators, have no easy way of generating views them. think possible?

you have specific situation - given dynamic nature of code-gen vs code-first models -and @ladislav mentioned. i'm not sure there 'easy answer' if @ all.

normally can make views @ (pre)compile-time - e.g. ef power tools. that's not going work you.

'edmgen.exe' utility of that, automating somehow may 1 option - haven't tried, , challenge given have.

t4 templates - other option.
best source of info require - how use t4 template view generation

however i'm not sure if that's going help either. problem needs edmx model generated in first place - , that's done hand.

now, invoke tool - or try sort of 'reverse engineer' edmx model somehow - , see how it's constructed ef in first place. i'm not sure, it's bit 'speculative'.

here post made know on edmx reader/writer, , how can use that. not sure, maybe expands horizons bit:)
ef 4.3 code first migrations - uncompress __migrationhistory model

also can link in more info how access metadata code, via dbcontext, again i'm not sure if of use you, need info 'before hand'.

and you'll need engage ef source code, able follow , understand how works, , how need, if haven't already.

r - Update two sets of radiobuttons reactively - shiny -

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
