OK, your 3.23s compares with my 2.7s for 5.10.0+2.18, and I get 0.7s for 5.6.0+1.0.10, which compares with your 0.87s. (All using the system malloc.) So your 5.6.0 set-up never gave you times like those I've seen with perl's malloc anyway. The difference that you're seeing is similar to what I saw between 5.6.2 and 5.10.0 (both using Storable 2.18): 0.9s up to 2.7s. I've no idea what causes this difference, but if you can live without the fork() emulation then switching to a perl built with perl's malloc definitely gives a big speed-up in both 5.6 and 5.10. ________________________________ From: Clinton Pierce [mailto:clintp@gmail.com] Sent: 30 January 2008 14:35 To: perlbug-followup@perl.org Cc: Steve Hay Subject: Re: [perl #50352] Perl 5.10 Storable extremely slow for large trees of data Using the supplied data file: C:\temp>\perl\bin\perl.exe xmledit.pl Retrieved.
