I noticed in the CHANGES file you wrote: Improve data throughput when using compression in dump by allowing multiple slaves to compress in parallel. Thanks to Phillip Susi <ps...@cf...> for the patch. Compression was already done in parallel, what I did was make the reading NOT be done in parallel because that usually slows things down. I have noticed that on a well aged and fragmented filesystem, the old way can be a little faster, I presume because the IO is more random and having multiple slaves generating IO concurrently gives the IO elevator more to work with so it can derandomize it some. On two unrelated notes: 1) I was wondering if you might consider upgrading to a modern VCS; CVS is just terrible. 2) I noticed that http://dump.sourceforge.net/ still says that the latest release is 0.4-b43. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJP/JJIAAoJEJrBOlT6nu752NkH/1q8rSsy8m7iU13eQ+C0n3ad gisaXFxTP+9/NeoxlXU9pUTcSxWvYqNCmEoDJrPVV/4klXex4IA0YGl8bPXT0Txc R3gfdzHGgeMVta+Er6A1akchokrmgLtBc/q1wu91yd+E2BxQtxeu2QYFN90tkK4I n+ls5GqMoSDQ+AdUUlW78o6o2zIV3I8ZcgIMBqB/GXY5CoNSV05+4/KmHLmEusIP axlz0lsamtsLcS3y2wMugwD8eFTRgp1oZdpSGJ8+Xfe1zd+GFwA4YJqK4Qs2OGsX NE1C8yzSv+WnyyCF+SkiVeywuRatlHCNSGeXaKhW1+a7EF4yQf7t+z1KtFqpFpc= =nsMF -----END PGP SIGNATURE----- |
