benchmarks made showed 70% of time creating new resttamplate() messageconverters , wondered if it's safe create 1 set of converters , use across multiple instances, different threads. edit: motivation logging "on wire" traffic. thought implementing using clienthttprequestinterceptor . since each request should logged different file, thought create new resttemplate each set of requests, different interceptor. this javadoc of httpmessageconverter doesn't explicitly require it, intention implementations thread safe. if thread safe, safe use across multiple resttemplate instances. resttemplate other http client use. shouldn't typically need more 1 instance per application. (some exceptions exist proxies, ssl configurations, etc.)

i'm learning multithreading, threads, threadpools, , such. have read number of threads cannot more number of logical processors computer has (or @ least there no advantage gained since cpu cannot handle more). so expected behavior if write code created hundreds of threads on computer say, 12 logical processors? queue up? wait each other? or give error? if have process benefit 100 continuously running threads, have 12 cores, best way handle this? open task manager see hundreds of processes , thousands of threads running. how work? also, if i'm running program in windows, bunch of other applications running (ie. chrome, ms excel, skype, ect...), , perhaps bunch of background services (ie. windows defender, wifi services, ect...) these other applications take logical processors, decreasing number of logical processors available threaded program? as thilo hinted at, modern personal computers perpetually creating, executing, , destroying dozens if not hundreds of th...

i have 2 pandas dataframes df1 = b c 1 2 3 2 3 4 3 4 5 df2 = x y z 1 2 3 2 3 4 3 4 5 need map based on data if data same map column names enter code here output = col1 col2 x b y c z i cannot find built-in function support this, hence loop on columns: pairs = [] col1 in df1.columns: col2 in df2.columns: if df1[col1].equals(df2[col2]): pairs.append((col1, col2)) output = pandas.dataframe(pairs, columns=['col1', 'col2'])
