c# - High CPU usage when sending data using SOAP -



c# - High CPU usage when sending data using SOAP -

we wrote in c# webservice sends , receives info remote clients. works fine. few days ago found when sending client array of bytes cpu usage increases 2% 30% on iis worker process. during debugging found cpu usage peak occurs after our webmethod ended, nil in our code. there don't know cause such cpu usage? when sends error code there no such peak...

this cpu usage occurs when there 1 client connected. when had 4-5 clients connected cpu used in 100%!

with little go on, i'm assuming (educated) guesses.

here's mine: check if gc active (you can in perfmon). if was, allocating/deallocating lots of memory? have long running transactions?

maybe of interest:

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
