Есть VPS 12 ядер 8Гиг. На ней висит чат-бот для вк (до 100rps в пике). Наблюдается много сбоев в ответах сервера

gunicorn запускаю так (через supervisor):
gunicorn --bind "unix:$BASE_DIR/world/var/run/guni.sock" \
--pid="$BASE_DIR/world/var/run/gunicorn.pid" \
--log-file "$BASE_DIR/world/var/log/gunicorn_stdout.log" \
--timeout=20 \
--workers=25 \
"basic.wsgi:application"
В чем может быть причина сбоев? Сервер слабый? Конфиги не оптимизированы?
ПРофайлер показывает что код выполняется за 150-200мс. (на SQL - 50мс уходит).
