I did a memory upgrade to 1.5g, the machine was still a bit sluggish because of the flash so I installed EWF filter. Man, what a difference. It makes the machine much smoother. After about 24 hours, the ewf cache is at about 58M. Of course, it will eventually fill up memory and probably cause some issues then. What has your experience been with EWF? How long were you able to go with normal browsing/email without the cache getting too full?
