Re: Speed up unbundling of hg bundles



Hi Thomas,

Is it not possible to use "hg clone ..." like "git clone" and not have to run for 20 hours or more?

Such a slow download would make users give up on NetBSD.

Where do you get the long name of that file to download?

You shouldn't have to use ftp for hg any more than you'd use ftp for a git-clone.

I remember that I had discussed the problem here before. At that time I had tried direct cloning, which had taken 11 hours or more. At that time, the cause was that my internet connection was unstable, which apparently led to the cloning mechanism getting out of step more often. As a possible solution, a user recommended to me at that time to go the way just described, i.e. to download an initial bundle from the CDN and unpack it via HG unbundle. I must admit that it is slowly dawning on me what the problem could be today. Then, at that time, unbundling was not so extremely lengthy, according to my memory. This time the signs are different - I'm trying to unbundle it on a ZFS dataset. If ZFS was the bottleneck, however, I would have expected the system to be 100% accounted for in Top. Instead, it is still the User Python process at the moment, which is why I thought that certain transformations are simply being carried out here, which are simply computationally intensive and therefore take so long....

Kind regards
Matthias
