Por algum motivo, o preenchimento automático é muito lento para mim no WSL, sempre leva vários segundos para exibir o resultado de, por exemplo, ll ~/Te<tab> (que, após 2-3 segundos, imprime ll ~/Temp ).
Eu tentei encontrar a causa usando set -x e strace , mas não consigo ver qual é o problema.
Com set -x (veja a saída abaixo), ele está parando na linha + [[ ~/Te == \$* ]] e, em seguida, novamente em + xspec=
Com strace , ele está pausando nas linhas clone e, de fato, mostra que está levando cerca de 1,4 segundo nessas linhas.
Alguma ideia do que poderia ser o problema?
