Hello Joel, use enclosed unstuff.hs ghc -O2 --make unstuff.hs -o unstuff -lz ./unstuff trace.dat +RTS -s -A10m analysis: 1) are you really don't use -O2 switch? :) 2) your origianl program spend 2/3 of it's time in GC. so i used -A10m to reduce GC times 3) i also placed lock around `unstuff` call to decrease GC times 4) small delay between starting threads allow each thread to start smoother of course, try these changes in your real networking code -- Best regards, Bulat mailto:bulatz@HotPOP.com
