It seems like you are traversing the list of thousands of objects many times, and maybe even copying lots of objects too!
So would it be faster to only traverse the objects once? So something like this
NEXT_OBJ:
foreach my $obj (@objects) {
foreach my $filter (@filters) {
next NEXT_OBJ unless $filter->($obj);
}
push @results,$obj;
}
I think there's a smart way to do that with iterators/closures too, but I don't know how fast it would be.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
