Process Lasso v9.1.0.28

Verfasst vonpipin

Pro­cess Las­so ist ein auto­ma­ti­sier­tes Win­dows Pro­zess­ma­nage­ment- und Opti­mie­rungs-Tool für Win­dows Vis­ta, 7, 8 und 10, das die Reak­ti­ons­fä­hig­keit des Sys­tems — beson­ders bei hohen Pro­zes­sor­aus­las­tun­gen — durch einen eige­nen Algo­rith­mus posi­tiv beein­flus­sen soll. Neben einer kos­ten­pflich­ti­gen Pro-Ver­si­on sind zusätz­lich eine Ser­ver Edi­ti­on, sowie älte­re Ver­sio­nen für Win­dows XP und Win­dows 2000 verfügbar. 

Mit der Ver­si­on 9.1 wur­de die Funk­ti­on “Ins­tance Balan­cer” ein­ge­führt, mit der man ein­zel­nen CPU-Ker­nen meh­re­re Instan­zen der­sel­ben Anwen­dung zuwei­sen kann. Dies geschieht über einen aus­wähl­ba­ren Algo­rith­mus. Der­zeit besteht die Opti­on, jeder Instanz ent­we­der die glei­che Anzahl von CPU-Ker­nen zuzu­wei­sen oder jeder Instanz eine bestimm­te Anzahl von CPU-Ker­nen zuzuweisen.

The Ins­tance Balan­cer indi­vi­du­al­ly assigns CPU cores to mul­ti­ple ins­tances of the same appli­ca­ti­on. This is done by way of a sel­ec­ta­ble algo­rithm. Pre­sent­ly, the opti­ons are to eit­her give each ins­tance an equal num­ber of CPU cores (reba­lan­ced when the ins­tance count chan­ges), or to set give each ins­tance a spe­ci­fic num­ber of CPU cores.

This new fea­ture is not some­thing most peo­p­le will need, but it covers a pre­vious gap in func­tion­a­li­ty. While users could set per­sis­tent CPU affi­ni­ties for dif­fe­rent appli­ca­ti­ons, mul­ti­ple ins­tances of the same appli­ca­ti­on were pro­ble­ma­tic becau­se they have the same pro­cess name and path.

Win­dows has a par­ti­cu­lar­ly bad pro­blem deal­ing with threads that deci­de they want to con­su­me every bit of CPU time they can get their hands on (CPU bound threads). A sin­gle CPU bound thread run­ning at Nor­mal prio­ri­ty can bring an enti­re sin­gle-CPU sys­tem to a stall, as demons­tra­ted by our gra­phi­cal pro­of of con­cept below. Yes, it is true – belie­ve it or not! It is this worst case sce­na­rio that Pro­cess Las­so was ori­gi­nal­ly writ­ten to address. By tem­po­r­a­ri­ly lowe­ring the prio­ri­ty of the offen­ding pro­cess, your PC can be saved from a full stall.
