# Descricao
7+
Uma quer que usei muito para trazer estatísticas de execução, para ter uma visão rápida de tudo que estava rodando no servidor a qualquer momento.
8+
Com essa query vc sabe a quantidade de requisicoes rodando, o tempo da mais antiga, quantas estao rodando de fato, quantas estao esperando cpu (runnable), em wait, etc.
9+
Pra um visão rápida, sem muita precisão, é uma boa consulta.

Por anos, essa query foi minha sp_whoisactive.

Antes de conhecer a sp_whoisactie (e mais tarde a PowerIsActive, do power alerts), eu usei muito isso aqui para saber como estava o servidor.
9+
Uma query que me trazia as infos básicas de tudo que estava rodando. Me ajudou muito a responder rapidamente a problemas de várias natureza (locks, cpu, disco, etc.)

Uma query simples para comparar as estatísticas de execução de procedures.

Ali one tem "nome proc" você especificar o filtro para achar as procs (E bancos)... Especificando mais de uma, você pode compará-las...
9+
Útil para comparar o desempenho de uma proc X e Y, sendo que a Y foi uma versão otimizada de X que você quer testar.
