Hi Ihor, it never occurred to me that bulk archiving could be sped up by changing anything about the archive files. i assumed that archiving worked by appending to those files, so once the initial find-file was performed, there should be no additional slowness.
yet i tried a new file with no archive file, and bulk archiving took less than a second for 9 entries. before it would take idk a minute. i will keep in mind disabling font lock in archive files. any suggested code for that? your config is impressively [and for me dauntingly] comprehensive. the Archiving anchor does not seem to have a referent. I searched for archiving, but didn't seem to find what you were probably pointing me to. thanks.
