Foreword

WhenIjoinedtheCommonLanguageRuntime(theruntimefor.NET)team

morethanadecadeago,littledidIknowthiscomponentcalledtheGarbage

CollectorwasgoingtobecomesomethingIwouldspendmostofmywaking

momentsthinkingaboutlaterinmylife.AmongthefirstfewpeopleIworked

withontheteamwasPatrickDussud,whohadbeenboththearchitectand

devfortheCLRGCsinceitsinception.Afterobservingmyworkformonths,

hepassedthetorch,andIbecametheseconddedicatedGCdevforCLR.

AndsomyGCjourneybegan.Isoondiscoveredhowfascinatingthe

worldofgarbagecollectionwas-Iwasamazedbythecomplexandextensive

challengesinaGCandlovedcomingupwithefficientsolutionsforthem.As

theCLRwasusedinmorescenariosbymoreusers,andmemorybeingoneof

themostimportantperformanceaspects,newchallengesinthememory

managementspacekeptcomingup.WhenIfirststarted,itwasnotcommon

toseeaGCheapthatwaseven200mb;todaya20GBheapisnotuncommon

atall.SomeofthelargestworkloadsintheworldarerunningonCLR.How

tohandlememorybetterforthemisnodoubtanexcitingproblem.

In2015weopensourcedCoreCLR.Whenthiswasannounced,the

communityaskedwhethertheGCsourcewouldbeexcludedintheCoreCLR

repo-afairquestionasourGCincludedmanyinnovativemechanismsand

policies.Theanswerwasaresoundingno,anditwasthesameGCcodewe

usedinCLR.Thisclearlyattractedsomecuriousminds.AyearlaterIwas

delightedtolearnthatoneofourcustomerswasplanningtowriteabook

specificallyaboutourGC.WhenatechnologyevangelistfromourPolish

officeaskedmeifIwouldbeavailabletoreviewKonrad’sbook,ofcourseI

saidyes!

AsIreceivedchaptersfromKonrad,itwascleartomethathestudiedour

GCcodewithgreatdiligence.Iwasveryimpressedwiththeamountofdetail

covered.Sure,youcanbuildCoreCLRandstepthroughtheGCcode

yourself.Butthisbookwilldefinitelymakethateasierforyou.Andsincean

importantclassofreadersofthisbookisGCusers,Konradincludedalotof

materialtobetterunderstandtheGCbehaviorandcodingpatternstousethe

GCmoreefficiently.Thereisalsofundamentalinformationonmemoryatthe

beginningofthebookanddiscussionsofmemoryusageinvariouslibraries

towardtheend.IthoughtitwasaperfectbalanceofGCintroduction,

internals,andusage.

Ifyouuse.NETandcareaboutmemoryperformance,orifyouarejust

curiousaboutthe.NETGCandwanttounderstanditsinnerworkings,thisis
