[Technik] FastCGI (Benchmark)

[Michael Hierweck]

Hallo,

ich habe auf h51 (dedicated server) mit FastGI experimentiert. Dazu habe
ich das folgende Paket verwendet:

Description: Shared library of FastCGI
 FastCGI is a language independent, scalable, open extension
 to CGI that provides high performance without the limitations
 of server specific APIs.

Probeweise habe ich das Bash-Skript durch einen gepatchten phpstub (in
C) ersetzt. Der Performancegewinn war marginal: in der Summe ca. 0.5
Sekunden für 1000 Requests.

Soweit nur zur Information.

Ich würde gern wissen, wie sich FastCGI in Bezug auf die Gesamtleistung
unserer Shared Hives auswirken würde.

Viele Grüße

Michael
