Better way to get job ID#?

System

I have the following code in a CGI task:

 open(QUERY,">$iwhome/tmp/activetasks.xml");
 print QUERY "<taskquery><active/></taskquery>";
 close(QUERY);

@activetasks = qx|$iwhome/bin/iwquerytasks < $iwhome/tmp/activetasks.xml|;
 unlink("$iwhome/tmp/activetasks.xml");

 foreach $lcl_taskid (@activetasks) {
  chomp($lcl_taskid);
  $lcl_task = TeamSite::WFtask->new($lcl_taskid);
  $lcl_wfid = $lcl_task->GetWorkflowId();
  print qq^
<tr>
 <td align=left>$lcl_taskid</td>
</tr>^;
 }

So, I'm trying to get the job ID that belongs to each in a list of obtained task ID's. The problem with my code above is that GetWorkflowId() is painfully slow when executed in a loop, as this is. There are currently about 25 active tasks and the cost of each GetWorkflowId is about a second. Any idea why this is? Or, if this is expected behavior, how can I optimize this?
