Немного статистики XML-файл источника составляет около 50 МБ. Число идентификаторов в исходном файле - 2962. Я использую xsltproc для Linux.
Я использую программу python, чтобы сначала получить все идентификаторы из исходного XML. Затем для каждого идентификатора, собирая название и статус из исходного XML. Это преобразование занимает приблизительно 2 часа на 4-процессорном ящике с 8 ГБ ОЗУ.
Мой вопрос: есть ли что-то, что я мог бы сделать для улучшения XSLT, чтобы уменьшить время преобразования?

Я думаю, что у вас есть какая-либо надежда на значимый ответ, вы должны включить некоторый образец ввода XML и соответствующий желаемый выходной XML. Также покажите ПОЛНЫЕ файлы xsllt. –
Я это знаю. Нам нужно увидеть фактические образцы. Также я сомневаюсь, что вам нужно использовать два прохода. Читайте на '
добавил файл образца к вопросу. – praving5
