android - too much work for one thread(database performance) -

-

at moment develope android app receives data bluetooth , store these data in local database. therefore wrote class called datamanager manages local database (inserts, reads, deletes...). first checked needed time save local generated data. storing 10000 objects takes 100ms. if receive data bluetooth , store it, takes 1700ms. not fast enough because receive 10000 objects per second.

i think it's because receive , store work 1 thread. call datamanager inside thread receives data bluetooth.

now asking myself how speed storing while receiving data?

i tried call store function of datamanager class in asynctask, more slow without asynctask.

how can speedup storing operation during receiving? bounded service storing? can use multi cores?

i happy recommendation

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
