So, I wrote a quick one for your case, where splitting as blocks is on the run scanning each lines without having to store any data or predetermine any stuff
I hope this should improve performance. If you have some time, please post some stats
Code:
#! /opt/third-party/bin/perl
use strict;
use warnings;
my ($input_file) = @ARGV;
open(my $lfh, '<', $input_file) or die "Unable to open file:$input_file <$!>\n";
my $start = 0;
my $curr_file_number = 1;
my $rfh;
my $data;
while ( $data = <$lfh> ) {
print $rfh $data if ( $start == 1 );
if ( $data =~ /#Game No :/ ) {
my $running_file_name = "tyrant_" . $curr_file_number;
open($rfh, '>', $running_file_name) or die "Unable to open file : $running_file_name <$!>\n";
$start = 1;
print $rfh $data;
next;
}
if ( $data =~ / wins / ) {
close($rfh) or die "Unable to close file <$!>\n";
$start = 0;
$curr_file_number++;
}
}
close($lfh);

ah a perl script. I tried to avoid learning perl, but if it's significant faster then bash tools there is maybe no way around ?
Code:

Unable to close file <Bad file descriptor>
I have "inherited" a OmniOS (illumos based) server.
I noticed rsync is significantly slower in respect to my reference, FreeBSD 12-CURRENT, running on exactly same hardware.
Using same hardware, same command with same source and target disks, OmniOS r151026 gives:
