Итак - итоги изысканий FPC vs. Java
на сервере FreeBSD 6.3 ( RAM - 64Mb, HDD 3G, on VirtualBox 3.x )
Испытатель: ab.exe (from Apache 2.2 on Windows) - 1000 запросов
FPC 2.4.0 - взят обрезанный пример из ExtPascal ( модуль fast-cgi на Apache 1.3.x mod_fastcgi )
- выводит только простой текст "Hello World!"

Сервлет - живой и легко прошел повторный аналогичный тест ...
Думайте и решайте сами ...
Не свойственно для консольного приложения явно косяк вида
