Hello, I have troubles profiling my EPG grabber. The profile log is: -------------------------- Thu Feb 8 17:14 2018 Time and Allocation Profiling Report (Final) tv_grab_fr +RTS -pa -hc -i1 -RTS --days 1 --output-file /res.xml total time = 103.35 secs (103353 ticks @ 1000 us, 1 processor) total alloc = 7,602,130,080 bytes (excludes profiling overheads) COST CENTRE MODULE SRC %time %alloc ticks bytes GC GC <built-in> 50.5 0.0 52166 57504 parse Text.HTML.TagSoup.Specification src/Text/HTML/TagSoup/Specification.hs:35:1-19 15.4 15.2 15879 1159030944 output Text.HTML.TagSoup.Implementation src/Text/HTML/TagSoup/Implementation.hs:(80,1)-(142,44) 13.5 22.9 14000 1743780696 expand Text.HTML.TagSoup.Implementation src/Text/HTML/TagSoup/Implementation.hs:(49,1)-(60,30) 11.6 39.0 11976 2962740856 -------------------------- Further in the log, I see: TvGrabPrograms.mySccGetProgramDetails TvGrabPrograms src/TvGrabPrograms.hs:69:1-17 5000 19 0.6 2.2 42.3 79.2 640 165979512 ~/= Text.HTML.TagSoup src/Text/HTML/TagSoup.hs:103:1-25 5543 135987 0.1 0.0 28.5 44.4 54 3263688 ~== Text.HTML.TagSoup src/Text/HTML/TagSoup.hs:(87,1)-(99,21) 5544 135987 0.5 0.3 28.4 44.3 485 19485856 parseTags Text.HTML.TagSoup.Parser src/Text/HTML/TagSoup/Parser.hs:16:1-41 5545 135987 0.0 0.0 27.9 44.1 44 0 parseTagsOptions Text.HTML.TagSoup.Parser src/Text/HTML/TagSoup/Parser.hs:25:1-39 5546 135987 0.1 0.1 27.9 44.1 138 7615272 parseTagsOptions Text.HTML.TagSoup.Manual src/Text/HTML/TagSoup/Manual.hs:12:1-54 5547 135987 0.4 0.3 27.7 44.0 422 22845912 output Text.HTML.TagSoup.Implementation src/Text/HTML/TagSoup/Implementation.hs:(80,1)-(142,44) 5548 135987 8.0 13.1 8.0 13.2 8221 994675336 -------------------------- But I see no function (~/=) calling (~==) calling parseTags in my code. The only line using parseTags is: let !tl = parseTags $ L8.unpack $ responseBody httpRsp Did I miss something ? Thanks in advance, Fabien
