Hi Adam, I can't see any obvious issues with your C code, so I assume the speed differences really stem from libdbi, one way or another. Unfortunately I currently lack the time for any deeper analysis, but I'm somewhat surprised about your results. libdbi has originally been developed as a wrapper for MySQL and PostgreSQL and should work fairly well with these database engines (other engines are a *lot* harder to fit). The only overhead that the mysql driver contains is the column type analysis and data conversion stuff. Some other engines have to buffer the data and thus create way more overhead. Did you have a chance to verify your results with any of the other database drivers? regards, Markus -- Markus Hoenicka http://www.mhoenicka.de AQ score 38 ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2d-c2 _______________________________________________ libdbi-users mailing list libdbi-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libdbi-users
