Ich habe mir kürzlich einen neuen dedizierten Server geschenkt und versuche, aus Spaß und zum Lernen die maximale Leistung herauszuholen.
Ich versuche, die maximal möglichen Anforderungen pro Sekunde zu erreichen, die dieser Server verarbeiten kann, und strebe 500.000 Anforderungen pro Sekunde an, wie hier erwähnt - http://lowlatencyweb.wordpress.com/2012/03/20/500000-requestssec-modern-http-servers -sind-schnell /
Serverdetails
Intel® Xeon® E3-1270 4 Kerne (8 HT) x 3,4 GHz
RAM 24 GB DDR3 ECC
Festplattenspeicher 2.000 GB (2 x 2.000 SATA) RAID-Software RAID 1
Lan 100 MBit / s
OS Centos 6.3 64 Bit
Nginx
Ich kann nur 35 KB Anfragen / Sek. Für eine statische TXT-Datei erreichen. Ich führe den Benchmark auf derselben Maschine aus. Ich kenne die NIC-Grenzwerte und den Netzwerk-Overhead
ab -n100000 -c200 http://localhost/test.txt
Update - 165K Anfragen / Sek
Ich habe ein anderes Benchmarking-Tool namens ausprobiert wrk
und es gab mir 165.000 Anfragen / Sek. So cool!
Update 2 - 250K Anfragen / Sek
