I've killed the process. Given that it takes only a minute or so to remove duplicates from about 2k keywords about 2 hours of 100% cpu usage(one core) for 16k keywords certainly is too much and seems to be a bug.
However DON'T GET ME WRONG the developer did a great job developing this software and I greatly appreciate it, and for the price given it's a steal and I AM SO HAPPY that I could have purchased it for this price. thanks alot!!!! I am just pointing to a bug( I know how nasty bugs can be, you can't anticipate everything...).
btw - I have a feature request:
there is a plugin that checks the serps for the "competition" as in how much pages rank for the given keyword. I often find myself in a position where I do want to get statistics for a given keyword like they are provided by traffic davis or market samurai, that are:
for the top 10 sites: pr, domain age, domain backlinks, page backlinks, keyword in url, number of edu / gov backlinks, onpage seo (h1, title, keyword density, etc) and a overall rating that analyzes this data.
I found NO software that does a check for these values for the top ten of a given keyword automatically and WITH given PROXIES.
since scrapebox does anything with it's proxy list...and since these queries are... relatively easy to implement... it would be SUCH A KILLER AND TIME SAVER to make a plugin for scrapebox that does this kind of analysis. I would even help developing it. (tell me the programming language etc

) Unfortunately the wonderwheel search is not saved in the folder harvester_sessions as far as I can tell.( I guess the same is true for any other plugin.)
another feature request:
when getting proxies, the first thing that should be done automatically (maybe an option to set it to manually for whatever reason) should be to remove duplicate proxies - it seems just to be a logical task that 99% of users should do before testing proxies. I wonder if there is any other way to check for duplicate proxies since this is very cpu consuming... but I can be wrong.
anyways, thanks for developing such a great tool. keep it up!!!
