Practical assessment of remotely communicated end-point servers of leading web crawlers

Exploration of future dreams inclined us in information quest over the global literature. Web crawlers enriched with technological phenomena for such purpose to millions of seekers. The usage of crawling tools implicates justification for their consequences as searching technology that facilitates initiative passion to target new information. Several web crawlers are available with different technological mechanism of remotely communicated servers; but their efficiency in terms of different performance metrics has been an open question. Previous studies provide inadequate comparison with limited analysis factors against these servers. Here we put an effort and provided new results by considering several performance metrics under practical estimation of technical factors with maximum capacity to evaluate foremost crawling technology based end-point servers. We extensively studied remote servers running behind Google, Yahoo, MSN, Gigablast, Mamma and Excite. We reflected their performance in terms of response time, load, health status, down time, uptime, availability and reliability. These new results would provide a deep insight to every researcher regarding to searching usages and related technological enhancement in future.
