Machine independent performance.

Hello, I have got a problem with performance.

My friend which is novice in Linux started with building a db application.
He use PostgreSQL. The application with a lot of queries, slects and updated
is slow, about 10minutes in a particular place. The speed is equal even if I
run postmaster on 80486,16Mb or Pentium,512Mb. It runs on RadHat 7.0, kernel
2.2.16. Compiled with --enable-multibyte --enable-locale. It use odbc, the
application is wrote in Centura Builder.

BUT: I started to instal my own installation of Linux, I downloaded
PostgreSQL and builded. Created db, and loaded data. Then I started
Postmaster and the same procedure takse NOT 10Minutes but 45second. I dont
know why in his instalation it is so slow. I do not know where is problem.
Also on Cygwin it runs about 45seconds. I Used RedHat 6.2.

I don't know where is problem.

The only diference I found was when postmaster was run with -d 2 parametr
was:

Slow instalation (10minutes): postmaster: ServerLoop:        handling reading 5
Quick instalation (45 seconds: postmaster: ServerLoop:        handling reading 8
