speedunitsandthemaximum'pages'perminutetoallrunningjobsinproportiontothenumberof
enginestheyareusing.
Note: Output speedisthespeedatwhichtheoutputiscreatedbytheengineinquestion.Data
mappingandotherstepsinaproductionprocessarenottakenintoaccount.Thethroughput
speedisthespeedoftheentireproductionprocess.Thiswillalwaysbelowerthantheoutput
speed.
Launchingmultipleengines
Onesingleenginecanonlyprocessasinglejobatatimeandwillrunmostlysingle-threaded.
Inordertobenefitfrommulti-coresystemsitisrecommendedthatseveralenginesruninparallel.
Asaruleofthumb,youwillwanttorunonelessengineintotalonamachinethanthesystemhas
cores,leavingoneCPUcorefreefortheConnectServerandtheoperatingsystemtouse.
Modernhardwaretypicallyhasbothfullcoresandhyper-threadingorlogicalcores.Thelogicalcores
shouldnotbecountedasafullcorewhendetermininghowmanyenginestouse.Asaguide,count
logicalcoresforonly25%-50%ofafullcore.
Forexample:onanInteli7CPUthatcomeswith4coresand4additionalhyper-threadingcores,Win-
dowsTaskManagerwillshow4coresand8logicalprocessorsonitsperformancetab.OnaCPUlike
this,5or6enginescanbeconfiguredtoruninparallel.
Toconfigurethenumberofengines:
1. OpentheConnect Server Configurationutilitytool(see"ServerConfigurationSettings"on
page82).
2. UnderParallel Processing,gototheContent CreationtabandsetthenumberofMergeengines
forthevarioustasks.
3. GototheOutput CreationtabandsettheReservedWeaver(Output)engines.
See"Decidinghowmanyenginesofeachtypetolaunch"below.
4. ClickApplyorApply and Close.
Itisadvisedthatyoudo not configure more engines than can be backed by actual processing power.
Thisaddsoverheadwhilenotaddingprocessingpower.
Deciding how many engines of each type to launch
Whenjobsruninparallel,different typesofenginesmayrunatthesametime.Itdependsonthe
usagesituationwhichtypeofengineshasthebiggestimpactonperformance.
Themoreandthelargeroperationsofakindneedtobeperformedsimultaneouslywithsmalleroper-
ations,thesooneryouwillseeaperformanceincreasewhenusingmultipleengines.
