I suspect if this was a problem the zlib people would have added internal buffering ages ago. I find it hard to believe we're not the first application to use it this way. I suppose it wouldn't be the first time a problem like this went unfixed though. Is the zlib software actively maintained or was your earlier comment implying it's currently an orphaned codebase? -- greg http://mit.edu/~gsstark/resume.pdf -- Sent via pgsql-performance mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
