  1. Perl,Postmaster and CPU question??

    gabriel <gabriel@workingnetsp.com.br> — 2001-08-13T14:27:05Z

    hello all 
    
    I have a perl script that read a text file and 
    insert the data in a table...
    
    but when this script is runing the usage of CPU by postmaster grows to
    between 79 and 90 percent...
    
    there's something to do about it?
    
    thanks...

    And this is a problem because...  ?
    
    Honestly, you're doing a lot of work, why wouldn't the CPU be busy?

    Are you using COPY or a series of INSERTs?  If the latter, are you
    doing them all inside a transaction?  INSERTs not wrapped in a
    transaction will load the system a lot more due to transaction
    overhead and disk sync latency.
