Alguém entende essa grande diferença no tempo de processamento, ao usar um arquivo intermediário ou ao usar um canal? Estou convertendo tiff para pdf usando ferramentas padrão em um novo servidor squeeze debian. Uma maneira padrão de fazer isso é converter para ps primeiro.
Sem cano:
root@web5:~# time tiff2ps test.tif > test.ps
real 0m0.860s
user 0m0.744s
sys 0m0.112s
root@web5:~# time ps2pdf13 -sPAPERSIZE=a4 test.ps > test.pdf
real 0m0.667s
user 0m0.612s
sys 0m0.060s
com tubo:
root@web5:~# time tiff2ps test.tif | ps2pdf13 -sPAPERSIZE=a4 - > test.pdf
real 1m6.098s
user 0m15.861s
sys 0m50.9
Durante o último comando, o processo gs está em 100% o tempo todo.
Atualizar :
Aqui está uma saída strace para a geração ps:
