Verifying Local Data (rehash) slowing at the end ...

[valera_svl]

Hello!
Transmission 2.94 at FreeBSD-amd64-R10

Verifying Local Data (rehash) extremly slowing from start to the end of huge torrent (250GB+)
CPU usage is 100%, but performance is lowing and lowing more as progress is closing to the end of torrent.
250GB is being verifyng over 16 hours now
I am watching that picture every time as I use such size of torrent to rehash.

I have solved the problem.
In file verify.c code block

if (fd != TR_BAD_SYS_FILE)
{

uint64_t numRead;
if (tr_sys_file_read_at (fd, buffer, bytesThisPass, filePos, &numRead, NULL) && numRead > 0)
{
bytesThisPass = numRead;
tr_sha1_update (sha, buffer, bytesThisPass);
#if defined HAVE_POSIX_FADVISE && defined POSIX_FADV_DONTNEED
(void) posix_fadvise (fd, filePos, bytesThisPass, POSIX_FADV_DONTNEED);
#endif
}
}

I have changed with this:

if (fd != TR_BAD_SYS_FILE)
{
uint64_t numRead;
if (tr_sys_file_read (fd, buffer, bytesThisPass, &numRead, NULL) && numRead > 0)
{
tr_sha1_update (sha, buffer, numRead);
}
}

So, the problem is gone.
