in thread Perl threading stability?

<blockquot>I am not aware of any problems that that a threaded build of perl causes for non-threaded applications, apart from a minor drop in performance.

Not sure if you'd know, but I thought I'd ask; know how minor? or how impacting is it to currently non-threaded scripts?

One thing I do have to watch out about is this version will be put out onto approximately 350 servers. At this time, my data collection scripts, only, will be using it. The collections script is not to be threaded. The threading is more for the "server" side script which gathers all the data collection dumps and loads it into the database.

    I knocked up this random meaningless benchmark script:
    my $t; for my $i (1..10_000_000) { if ($i % 3) { $t += $i; } }
    and ran it a few times on a threaded and non-threaded perl build (a recent bleedperl) and got average timings of 4.46s and 4.99s, so about 10% slower.
