Is this reproducible if you run vim multiple times in a row for each file separately? How many times this file may be duplicated in your free RAM? I think this issue may be related to FS caches: sort requires reading the whole file into memory and has some overhead related to sorting, so it may just have forced FS caches to be dropped, while downloading this file has put it into the cache. -----BEGIN PGP SIGNATURE----- Version: APG v1.1.1 iQI1BAEBCgAfBQJUESmKGBxaeVggPHp5eC52aW1AZ21haWwuY29tPgAKCRCf3UKj HhHSviejEACh7LNmQJik5pU09q8by8FabZfCf2ctJjg7hQPcdciDWRbmCU6c8XCq APH1kgaW3Jq770IiSOQEWqMBC+Wqu+auHitGFMnjKkae0/KcnFeDYuNxn5+M3PbH ZG25dtJ/KyUTmPnE4mJvgykcbamn6nxZfM+KWk29Z/yHIi4j48AA0/iFXkG2thn0 33AsqEvrzo0Fgy2P6spWPLSCIdOT9ha4C+qHU06S74N4D4qVraa2QZ3mNCLL0Ocy FXfs1rpA/YpjaRtLkKxRmUbeP8yuar/nTxXsy+PFOybc8kYIpZuQIrticm99RntQ tiEllPav6xJNSq2j588HVxp7E2CB4LQZ3NBAxpIkXsHoIQxaRL2SQ1Wb1jpOfGP+ qIBm92UU61l4dhf+ECFNoM5CnWP/y3scHoPb9m04NK+CMHMm3Sgkj5ctKERJgDQu 23HG83Eo4vUruIim+aV54jBqiXrSjveHgHyU4lkmZlYs8JA8Hvu2L0asha1hN047 iwa7iw1W0tAorgmVALhmRKt16LKF2A+hYSERDZ3jjJu0j8QABH6GkiFJEjWXELGh +EaJYYbVKa81MAZfUsQ/Ti0gxOGLLH0g4MF7DotSc+UlewoyoyzuaxTSl7P2OPMa RHvBBT0WrUPF+xa/HOKILk6a9DIFPgwlJyAAa+eWTuijVP+8UMUO+g== =75KF -----END PGP SIGNATURE----- -- -- You received this message from the "vim_use" maillist.
