Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.17 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 21 Feb 2014 23:51:24 -0000 Hi, I have an application (the "texmacs" text editor) that was running fine under 9.2, but when I upgraded to 10.0, its response time slowed down drastically. I am running the same binary in 9.2 and 10.0. Running truss on it, I see on 10.0 that it spends a lot of its time calling gettimeofday: gettimeofday({1393022478.199440 },0x0) = 0 (0x0) recvmsg(0x5,0x7fffffffce60,0x0,0x7fffffffce90,0x806aabd90,0x8080808080808080) ERR#35 'Resource temporarily unavailable' gettimeofday({1393022478.199545 },0x0) = 0 (0x0) recvmsg(0x5,0x7fffffffce60,0x0,0x7fffffffce90,0x804817730,0x8080808080808080) ERR#35 'Resource temporarily unavailable' recvmsg(0x5,0x7fffffffce60,0x0,0x7fffffffce90,0x804817730,0x8080808080808080) ERR#35 'Resource temporarily unavailable' This didn't happen in 9.2. Has something changed in 10.0 with respect to gettimeofday? Most importantly, what can I do about it? Thanks. Kostas
