का उपयोग करते हुए nfsstat -c
, मैं एक उच्च "ऑक्ट्रेफ्रेश" (कुछ प्रणालियों पर "newcred" के रूप में जाना जाता है) को अपने एनएफएस क्लाइंट पीसी पर परिचालनों के लिए ls
और find
~ 1000 फ़ाइलों वाली निर्देशिकाओं पर गिन रहा हूं । यह बहुत खराब प्रदर्शन (20+ मिनट निर्देशिका लिस्टिंग) के साथ संबद्ध है। कैश्ड एनएफएस ऑपरेशन इस व्यवहार (ऑक्ट्रेफ्रेश या मंदी) को प्रदर्शित नहीं करते हैं।
हर बार जब मैं nfsstat की जाँच करता हूँ:
$ nfsstat -c
