Scrapebox issues. 100% CPU issue When Indexing.

Im using the latest update of scrapebox and i am trying to use the index checker to check url's for indexing. no matter how many threads i use, i always get 90-100% cpu usage. I can't figure it out. My vps is more than capable of handling scrapebox. Im only using scrapebox on this vps. Nothing else is being ran. I am using public proxies that are tested, 800 to be exact. I've tryed using only google proxies thinking that since im indexing for google i would need them, but this doesnt work either. I've tryed only using 5 threads and still 90% cpu. I'm drawling blanks here. There is another thread on here from like 5 years ago where someone was having a similar issue but the issue was never addressed. Someone please help. Thanks
