मुझे फ़ायरबर्ड में एक क्वेरी की गति के साथ समस्या है। धीमापन क्रमबद्ध और विशिष्ट में है।क्वेरी फ़ायरबर्ड धीमी ऑर्डर/विशिष्ट
यदि मैं MySQL में क्वेरी का प्रयास करता हूं तो वह एक सेकंड तेज है।
Firebird -> 0,3s एक 0,4s
हम एक वेब सर्वर/वेबसाइट पर Firebird डेटाबेस का उपयोग, इसलिए गति महत्वपूर्ण है -> एक 1,6s MySQL 1,3s।
विशिष्टता: - Firebird 2.5.1 या 2.5.2 (SuperClassic) 64 बिट्स - 2,13 GHz (2 प्रोसेसर) - रैम 4,00 जीबी
मैं क्या कर सकता है?
मैं निम्न तालिकाओं है:
