I have configured my fs with xml_curl module in the directory part, may serve 100,000 extensions from a single FS or is there any limitation as to the software?

IN the hardware I have a server with the following specifications:

Brand: DELL
RAM: 4GB
CPU: Intel (R) Xeon (R) CPU E5405 @ 2.00GHz
cores: 4
DD: 50GB

regards.
