I tried to renice clamd with a priority of 19. It doesn't change the behaviour of scanning while I'm browsing, and the reload process doesn't take more time ; I'd even say it's better since the load average doesn't climb as high as it did before. But, I still have a problem ; during the reload process, I can't browse ; as clamd is occupied to reload, it can't scan the streams. How could I do to still use it while it's reloading ?
