w3m uses OpenSSL rather than GnuTLS, I think.

Which version exactly of GnuTLS are you running? Is it possible for
you to do a local install of a newer version and try that with emacs?
Otherwise, maybe turning off TLS1.3 will help:
(setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3")
Another thing to try is setting 'gnutls-log-level' to progressively
higher values, to see if it resolves the timing issues.
