I have a modern laptop (quad-core i5 2.5GHz, 4GB RAM, ) at work. But it is very slow and unresponsive when I copy files in the background.On the other side, at home I have a simple 2-core PC (E2180 2 GHz CPU, 2GB RAM) and I do not observe any reduction of the performance whenever I copy anything. Both computers have similar HDDs installed and both tested using same file systems, operating systems and drivers. So, I am trying to understand what can cause such performance drop. Is it a typical problem of all laptops? According to PassMark chart table my PC should be 2-times slower than my laptop, but it's not the case: my PC is much faster under high I/O load. Do you know any reliable performance chart which takes into account this kind of tasks (file copy, I/O)?
Virus scanners in companies are notoriously slow. That's probably because the persons affected (employees) are not the persons who choose the virus scanner.
The person who chooses the virus scanner will not be fired for wasting 1 hour/employee/day, but might be fired if a virus gets through. So his best strategy is to make it look like he did everything possible, including cranking up the scanner settings to Ludicrous.
