Re: Strange performance issue

Thanks for confirming that

1 - there is a problem with 7.1.3 and I am not hallucinating, and
2 - it has been fixed!

It's possible that the 7.2 port won't work properly because of some
patch, I will test this after 7.2 enters the port tree as well.

Thanks for all the good work!

- Mike H.

   Testing your case with postgres 7.2b3 on FBSD 4.4-STABLE, I do not
   see what you described.  Below is a copy of top(1) running while
   running two instances of your script.

    9507 brent     41   0  5172K  3376K RUN      0:11 37.17% 28.47% postgres
    9508 brent     41   0  5172K  3376K RUN      0:11 36.98% 28.32% postgres
    9506 brent      2   0  4196K  3072K select   0:02  5.42%  4.15% perl
    9505 brent      2   0  4196K  3072K select   0:02  4.85%  3.71% perl

   running the same against 7.1.3 top(1) shows

    9575 pgsql     -4   0  6044K  3480K semwai   0:04  0.88%  0.88% postgres
    9574 pgsql     -4   0  6044K  3484K semwai   0:04  0.73%  0.73% postgres
    9580 pgsql     -4   0  6044K  3484K semwai   0:01  0.70%  0.68% postgres
    9579 pgsql      2   0  6044K  3484K select   0:01  0.15%  0.15% postgres


   cheers.
