I haven't ever really used GSA SER before since I've always been using tools such as SB, xRumer, SEnuke and Ultimate Demon, so I'm by no means new to the game. However couple of days ago I started using GSA SER along with GSA CB (only) as the captcha solver. I bought a 100% fresh link list and set up a new project and altered the settings to what seemed reasonable (all engines checked). I set up a catchall email that I redirected to outlook.com and set GSA SER to check emails every 15 minutes. I run on the following dedicated server (SSD hard drive): CPU: Xeon E3-1245 v2 GHZ: 3.4Ghz Cores: 4 / 8TH RAM: 32GB Bandwidth: 1Gbps Unmetered I set my thread count to 200. And loaded in 50 semi-dedi (but pretty fast) proxies. However I'm only able to achieve ~60 LPM and ~10 VPM which is very disappointing. After having searched around I realized that it is advised to run multiple projects to increase the speed of the links being built. This doesn't make any sense to me as I would assume that the thread pool (of 200) would dedicated be used for my single project instead of being shared between multiple projects which IMO should result in the same workload and thus the LPM/VPM should be equal. Can anyone tell me why multiple projects speeds up everything as opposed to dedicating GSA to 1 single project?
