Here are my timings for sorting a 600 Mb file after giving "sort" one Gigabyte of memory and a very large workspace. It used about 800 Mb of disc workspace and didn't make a dent in the memory. The unsorted file is random order but I also reverse sorted it to be sure that the test is representative.
This test server is nothing special - a 10 year old HP 9000 with HP-UX 11i and slowish 36Gb 10k rpm discs.
Are you sure that you file is only 200 Mb ?

After my previous thread, I think I found out what causes the long delays.
I run this program on several Linux computers, and the sometimes (after the file with the arrays becomes big) the fwrite takes between 100 ms to 900 ms.
This is very bad for me, as I want a timer to halt each 30 ms.... ... (5 Replies)

libapache2-mod-perl2-2.0.7::docs::api::APR::Date(3pm) User Contributed Perl Documentation libapache2-mod-perl2-2.0.7::docs::api::APR::Date(3pm)NAME
APR::Date - Perl API for APR date manipulating functions
Synopsis
use APR::Date ();
# parse HTTP-complient date string
$date_string = 'Sun, 06 Nov 1994 08:49:37 GMT';
$date_parsed = APR::Date::parse_http($date_string);
# parse RFC822-complient date string
$date_string = 'Sun, 6 Nov 94 8:49:37 GMT';
$date_parsed = APR::Date::parse_rfc($date_string);
Description
"APR::Socket" provides the Perl interface to APR date manipulating functions.
API
"APR::Date" provides the following functions and/or methods:
"parse_http"
Parse HTTP date strings
$date_parsed = parse_http($date_string);
arg1: $date_string ( string )
The date string can be in one of the following formats:
Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123
Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036
Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format
refer to RFC2616 for the details (GMT is assumed, regardless of the used timezone).
ret: $date_parsed ( number )
the number of microseconds since 1 Jan 1970 GMT, or 0 if out of range or if the date is invalid.
since: 2.0.00
Remember to divide the return value by 1_000_000 if you need it in seconds.
"parse_rfc"
Parse a string resembling an RFC 822 date. It's meant to be lenient in its parsing of dates. Hence, this will parse a wider range of
dates than "parse_http()".
$date_parsed = parse_rfc($date_string);
arg1: $date_string ( string )
The date string can be in one of the following formats:
Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123
Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036
Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format
Sun, 6 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123
Sun, 06 Nov 94 08:49:37 GMT ; RFC 822
