c# - Apparent ODBC recordset size limit -


platform windows 10.

i doing stress testing on 32 bit app using components purport intelligent caching large data sets built around adodb operations. have 64 bit postgresql v9.6 server installed using default user inputs, , i'm using psqlodbc 32 bit odbc driver offered installed during server install, , referencing driver through standard odbc connection set through 32 bit odbc control panel applet.

i loaded database table 5 million records testing. worked expected, know odbc connection , write new rows part of api working correctly.

the table has bigint primary key (bigserial actually) , text field contains key value formatted out take space. rows can seen , browsed in pgadmin4 app installs server.

in app, open recordset query:

select * mytable;

this takes 20 sec server process , control returned app ui. expected recordset count of 5000000. instead, recordset 84796 records in it.

can please explain might going on here, , how work around it, if possible? thanks.

need more info, ask.

cheers

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
