Well, yes, but the OS and the disk drive subsystem still cache the file (in this case, 150k worth). So, it's all still an approximation. I think the point is that for small files like this, most languages are fast enough. And since we're likely to be performing a database-related activity, the processing time and time updating the data (output I/O) is likely to overshadow the throughput of the input phase. But, as Ed always says, it is worthwhile benchmarking with your application, your data on your hardware to determine what's appropriate for the real world. -- Ted Roche Ted Roche & Associates, LLC http://www.tedroche.com _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/cacw6n4vbtb0pp6ftd-j-ptx5fqjm0qo71vmyvhy1wctgbic...@mail.gmail.com ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
