Some system mallocs are very inefficient on small blocks so it might be very worthwhile to grab a "chunk" of, say, 64k, instead of many small mallocs of 20 bytes. How do you propose that we should handle those systems, where the libc malloc is inefficient? -- Best regards, Per Lundberg / Capio ApS Phone: +46-18-4186040 Fax: +46-18-4186049 Web: http://www.nobolt.com
