Subject: bug#33708: 26.1.90; nhexl-mode performance
Date: Tue, 11 Dec 2018 18:06:40 +0100 [thread overview]
Message-ID: <8d6352ac-4bca-fb76-8c2f-dd597e481e8e@bgc-jena.mpg.de> (raw)
Filing a bug report because of the discussion on
https://emacs.stackexchange.com/questions/46492/how-to-search-for-a-sequence-of-bytes-in-hexl-mode/
nhexl-mode performance is really bad in large files.
Occurred in the files of the Bitcoin blockchain. The beginning of every
block is marked with the byte sequence `f9beb4d9`. Searching for this
byte sequence in nhexl-mode is really slow.
In case you do not have the bitcoin client installed, I uploaded the
first file of the blockchain here (134MB, link will be valid for 30
days):

Thanks for looking into this.
Guido.
