Merhabalar : Benchmark testleri hic bir zaman %100 sonuclar vermez fakat yeni bir sunucu yatirimi yapacaginizda size az bucuk fikirler verebilir , mesela dun yaptigim bir kac islemci testinden size bir kac enstantene sunabilirim ;

Gordugunuz gibi cok enteresan sekilde 2 islemcili 5430 2.66GHZ - 12gb ram DDR3 benchmark skoru : "4433.8" fakat Tek islemcili Xeon 3460 2.80GHZ Hyper-threading 8 cekirdek benchmark puani "5286.1".

Bu 2 sunucuyu yurtdisinda kiralamaya kalksaniz 2x5430 , 3460 'dan en asagi 100$ daha pahali , mesela bu testleri gordukten sonra 2X5430 sahipleri varsa 3460 'a gecmeleri onlara daha iyi performansi daha ucuza almalarini saglayacak.Tabiki Database uygulamarinda cache on plana cikacagi icin 2X5430 'un cache'si daha (2x12mb) fazla ve o tur bir operasyon icin daha uygun.

O yuzden bu tarz testler yapilmali ve arsiv olusturulmali.

iyi calismalar.
Kişisel olarak E5620 ve 55** serisini karşılaştıracak olursanız, pratikte gördüğünüz farkları söylemeniz mümkün mü? 55 serisinden cache olarak fazla olduğunu biliyorum ancak testler yine de kafamı karıştırıyor (: Tabi iki neslide çift işlemci olarak değerlendirelim.
