+/* On some platforms, malloc() performance is bad enough that you can't just |
+ * free() and malloc() buffers all the time, so we need to use freelists from |
+ * unused buffers. Currently, each freelist holds memory chunks of only a |
+ * given size (list->chunklen); other sized chunks are freed and malloced. |
+ * This doesn't help much if you're using many different SSL option settings |
+ * with a given context. (The options affecting buffer size are |
+ * max_send_fragment, read buffer vs write buffer, |
+ * SSL_OP_MICROSOFT_BIG_WRITE_BUFFER, SSL_OP_NO_COMPRESSION, and |
+ * SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS.) Using a separate freelist for every |
+ * possible size is not an option, since max_send_fragment can take on many |
+ * different values. |
+ * |
+ * If you are on a platform with a slow malloc(), and you're using SSL |
+ * connections with many different settings for these options, and you need to |
+ * use the SSL_MOD_RELEASE_BUFFERS feature, you have a few options: |
+ * - Link against a faster malloc implementation. |
+ * - Use a separate SSL_CTX for each option set. |
+ * - Improve this code. |
