mutt seems laggy to resume on v.2.x

[tech-lists]

Hi,

I'm finding mutt significantly more laggy to resume on later
versions (=>2.x) than say 1.5.21.


as responsive as it's always been before.

Then, say 5 minutes happen where nothing happens. Slow to move


Is it my config? Maybe should revise it as it's not changed
significantly for more than a decade. What should I be looking for?

For context:
freebsd-current (all debugging has been turned off)
TMP is ~/tmp and is tmpfs (memory) mounted.
$HOME is usb3-mounted spinning rust.

Let's say there's the list of emails in a folder already selected. If I use up or down arrow for example, it'll sit for 3-4 seconds doing nothing and then move. But once moving, it's around again. I'm using imaps. It's not having to re-authenticate, so the connection isn't dropping. Ping times to the imap server are 77ms, no packet loss. -HOMESPOOL +USE_SETGID +USE_DOTLOCK +DL_STANDALONE -USE_FCNTL -USE_FLOCK +USE_POP +USE_IMAP +USE_SMTP +USE_SSL_OPENSSL -USE_SSL_GNUTLS +USE_SASL -USE_GSS +HAVE_GETADDRINFO +HAVE_REGCOMP -USE_GNU_REGEX +HAVE_COLOR +HAVE_START_COLOR +HAVE_TYPEAHEAD +HAVE_BKGDSET +HAVE_CURS_SET +HAVE_META +HAVE_RESIZETERM +HAVE_FUTIMENS +CRYPT_BACKEND_CLASSIC_PGP +CRYPT_BACKEND_CLASSIC_SMIME +CRYPT_BACKEND_GPGME -EXACT_ADDRESS -SUN_ATTACHMENT +ENABLE_NLS +LOCALES_HACK +HAVE_WC_FUNCS +HAVE_LANGINFO_CODESET +HAVE_LANGINFO_YESEXPR +HAVE_ICONV -ICONV_NONTRANS -HAVE_LIBIDN +HAVE_LIBIDN2 +HAVE_GETSID +USE_HCACHE +USE_SIDEBAR +USE_COMPRESSED -USE_INOTIFY -ISPELL
