Here's a test which connects to a mysql db, creates a small table, puts a few records in it, and performs some sanity checks on the DB API (the code i'm developing - a db access abstraction layer)... ~> time tcc -run -Iinclude -I. -rdynamic -L/usr/lib/mysql -lmysqlclient -lsqlite3 -L$HOME/lib tcc-test.c -m Testing against DSN [mysql5:dbname=cpdo;host=localhost;port=3306;autocommit=true;fieldbuffersize=128;enablenamedparams=true;ignored=hi]... ... big snip ... real 0m0.080s user 0m0.020s sys 0m0.010s With gcc: real 0m0.070s user 0m0.000s sys 0m0.000s only 1/10th of a second slower. Interestingly... the same test against an sqlite3 database (exact same SQL operations, different back-end): ~> time tcc -run -Iinclude -I. -rdynamic -L/usr/lib/mysql -lmysqlclient -lsqlite3 -L$HOME/lib tcc-test.c -s Testing against DSN [sqlite3:my.sq3]... <snip> real 0m0.240s user 0m0.030s sys 0m0.000s gcc: real 0m0.199s user 0m0.000s sys 0m0.000s gcc is still only about 1/5th faster. (What i cannot explain, though, is HTF MySQL is faster (and so much faster!) than sqlite? The MySQL server and the sqlite3 db are on the same hard drive, so drive/system speed differences aren't a factor.) -- ----- stephan beal http://wanderinghorse.net/home/stephan/
