Extremelly slow hashing

[octagram-3]

Day after day I run Shareaza, but it progresses verly slowly. I see the picture like the attached one every day. GreyLink hashes everything with a speed of about 10Mbyte/sec due to the fact most of my files reside on SMB volume. Local files are hashed with a speed of about 60Mbyte/sec.

Shareaza will no doubt hash files slower because in addition to the most important TTH it also has to calculate ED2K, MD5 and SHA1. And also extract metadata. However, waiting a month to share 170Gb is way too much! Well, maybe change priorities? First of all, calculate TTH because nothing will work without TTH. TTH of every file so that my files can be maid available as soon as possible. When every file is available, let's do the rest: extract metadata, calculate ed2k, md5 and in the last order sha1.

Hashing is also related to your HDD condition. With such a big number of files I suppose that HDD defragmentation could help.

Today is the historic day. Shareaza finished hashing my files! I was so glad that I decided to wrote it here.

Most disk partitions are formatted in HFS+. They are accessed via SMB across VMWare host only network.

And, anyway, all this time GreyLink was always fast at hashing. Shareaza wastes time while file progress is 0%.

I think that in the previous forum somebody else also had performance problems with HFS+ partitions over SMB. IIRC he also did some troubleshooting on the cause and made a bug report on it. Unfortunately I think the report (and the discussion) was lost and I don't really understand SMB well enough to remember what exactly was the problem. Anybody else remember?

BTW, I usually hash files in smaller groups instead of all at once. It doesn't actually affect the hashing speed but having a long list of unhashed files seems to cause Shareaza problems, so I keep files to be hashed below one thousand and wait until it drops to few hundred before adding more.
